I'm close to this. Though I will caveat that for pickup, I rarely tip but the people there did something great I will do up to 10%.This quote is hidden because you are ignoring this member. Show Quote
For truly terrible service (the kind you leave, asking how that person even manages to maintain employment there) I will not tip at all to make a point.
Simply crappy service gets 10%. Most get 15%, and if it was great service I will do 20%. I've even done 25% on extreme occasion, but that's truly knock-your-socks-off-make-me-feel-like-a-king service.
