I’m getting irritated with how common it is for every service organization to now prompt for tips when paying electronically. A Venti plain Starbucks coffee is over $4 now. I’m sorry, I’m not tipping for that.
At some point small businesses, food carts, etc, realized that if you just put a tip jar on the counter, many people will throw money in it just because it's there. It's culturally expected now. I find it slightly infuriating.
