vegan, coeliac's, legume/bean
How can get any protein if she's vegan and can't eat beans or legumes??
I wonder how our American friends are handling this. Do you tip at all restaurants, including fast-food outlets? Do you tip taxi drivers, hairdressers, delivery guys, at bakeries (!!), and anyone who renders the slightest service (for which they supposedly receive a salary)? As a tourist, I would not be too thrilled about being constantly confronted with the expectation to tip.
I tip at all sit-down restaurants. 15-20%. That's been a thing as long as I've been alive although the recommended amount has crept up. 15% used to be standard, now it's 20%. Fortunately the traditional fast food restaurants (McDonalds, Taco Bell, etc) still don't allow tipping.
Most other chains such as Starbucks or Panera or Domino's may have a jar by the counter where one might deposit their change or a dollar or two.
But now payments at these places are mostly electronic and the payment system will display a prompt with easy select options to tip, such as None, 15%, 20%, 25% and Custom. So while you're doing that, the person at the register will look disinterested and pretend they don't care. (They probably really don't care but I always feel like they're waiting in judgement.)
The other confusing thing about tipping is that the distribution method differs. So you may think you're tipping the person who gave you service when it's really put into a pot and distributed to staff. It's illegal for business owners and managers to keep any of the tips but I sometimes wonder if the tips left at the Chinese take-away are really given to the staff, some who may be immigrants and possibly here legally.
Of course pizza, uber eats, etc. are tipped. That's one reason I never use delivery services. I'll just pick up my pizza myself. Which is ironic given my former career as a pizza delivery guy in which I appreciated the generous tippers. That was the only job where I ever received tips. I also worked inside making pizzas and sub sandwiches but we didn't get tips in those days. I don't even think we had a tip jar out. It just wasn't normal then.
And, yes, hair dressers. 20% is also standard. And prices have really gone up. Standard chain price is at least $20-$25 for a guy's haircut now. An actual salon will charge $30-$40 (plus tip). So I'll wait for a $15 coupon to appear and give a generous $5 tip. I'm always a little shocked by these guys that have hardly any hair, not even an inch long coming in for a full price haircut done the simple way with a hair trimmer.
