I used to always tip 20% when sitting down at a restaurant or bar, still do unless something is really off, but I would tip nothing or a lot less when picking up, unless I had a really good relationship and they'd hook me up. But then Covid hit and I tipped 20% everywhere for picking up because I was just glad they were open but also because I knew they were taking a risk and no one was allowed to dine-in so they wouldn't get their normal 20%, so I thought it was fair. Now they took a nice gesture and exploited it too much. I don't tip when picking up anymore.
