Obviously it means that it you want to open a restaurant, you have to own a bike first

I've determined it means that people who ride bikes are smart and rich.

This is all I can think of:

This guy makes christian comics.

On dude's site this one is called Popular vs Unpopular

and underneath it is the bible quote:

Better to be a nobody and yet have a servant
than pretend to be somebody and have no food.
Proverbs 12:9 NIV

From what I can tell she dates a guy who knows how a lady should be treated but can't actually afford to treat her that way.
From the woman's face in the 4th panel she has grown insecure and lowered her standards, dating a guy who bikes and takes her for a burger. She sees on going to the bathroom that her date owns the restaurant chain they are eating at.

The lesson seems to be for women to know their place and date men who could treat them as they deserve, but instead take them to a place they get kickbacks from eating at (and seemingly don't reveal this fact before inviting them).

Praise jay-sus.

Edit: Since the "loser" has dark hair and takes her to a sushi restaurant, and the "good" (presumebly christian) catch has blonde hair and takes her to an all-american burger joint, it also comes off as slyly racist—at minimum xenophobic.

I gotta admit, the artist really nailed that "Oh my god what did I get myself into" - nervous fake smile in the fourth panel

I think the moral is that love is transactional?

Pretty sure it's about conspicuous consumption and how many people live above their means.

In practice, there's many rich people who understand that flaunting wealth is seen as crass, and many who don't want to be known as well-to-do. There are definitely wealthy people who also understand how wealth can taint their interpersonal relationships, and aren't excited to share how wealthy they are initially with a new partner, because they want the partner to like them for who they are, not for their wealth.

The first man appears wealthy, but in actuality has very little money, because he has spent his money on things that make him look wealthy. He flaunts his "wealth" only for it to be a sham.

The second man appears poor, but in actuality has a decent amount of money, because he has spent his money on things that actually provide value, while limiting conspicuous consumption. He would prefer to initially hide his wealth from a new partner.

This isn't meant to be a defense of the rich. By and large, most rich people are all too happy to commit to conspicuous consumption and let their interpersonal relationships be tainted by money. The handful of rich who understand how money twists things I do not think are properly representative of the whole.

Give lower income people a chance. You never know which ones secretly own burger joints.

Why would you hang the opening day picture in the women’s bathroom?

Looks like a Dharman video Plot lol

If you try hard enough you can trick yourself into thinking it's loss

the bottom one she gets stood up because the guy was opening a restaurant and didn’t tell her

That's a picture on the wall.

the christian moral here is that if you’re a woman you get screwed over either way

Well, yeah. And you'll like it.

Eating sushi will break your pants and eating fast food will make you go to the bathroom. (Also please don't point at people with chopsticks.)

the message is own a burger joint so you dont have to pay for a date

That woman owns only one dress.

Imagine taking someone out to the McDonald’s location you own as a first date. Couldn’t they afford someplace nicer if they own a restaurant?

A woman seems to be the main character as well as the only one with an emotional arch.

People who flex their wealth are vain and selfish
