It's somewhat infuriating. You use to tip waiters/waitresses. They took your order and brought it to you. Now they ask for tips when they do none of that. Every non-chain fast food joint / coffee stand where all they do is stand at the cash register, take your order, and hand it to you, they now ask for a tip. The bakery asks for a tip. The taco stand asks for a tip.
On top of that, in SF, prices are off the chart. Went to a bread store. One loaf of bread + 1 canele + 1 coffee + 1 sandwich, $47. Got chinese dumplings. 3 people 3 plates of dumplings and 3 side dishes, $135 (with tip). That same thing would have been < $30 in Singapore, Hong Kong, Shanghai, Taipei. Even Japan
