Tipping in a coffee shop is just yet another way to obfuscate real pricing. Instead of asking $5 for a coffee they ask for $4. Then you have to pay tax, which for absolutely ZERO reason is not included in the price. You're at about $4.40. Then you tip and end up at anywhere between $5 and $5.50 in actual money you spent on your "$4" coffee.
