You are on a frugal community dude, do you not get the whole point is convenient ways to save money. Making your own coffee or not drinking coffee at all is a very worthwhile endeavor. It takes about the same amount of time as drive to a coffee shop and get a drink. The only plausible thing I can think of is that you are being sarcastic. Otherwise just leave this community alone, some people actually need help and I don't really think you would have any valuable insights.
