I'm completely flummoxed why several of those things make you an asshole customer, particularly the tea bags and the credit card split/tip thing (15% of $100 is $15, so if each pays $50, why wouldn't $7.50 be proper?). And if it's evil to explain a health condition *and* evil to bring your own tea bags, than doing so because of a health reason must make you like the Spawn of Satan or something. Which is good, always did want to have Satan for a parent.
