I picked up takeout and there were three tip options, the lowest was 18%. 
They didn’t even speak to me, just handed me a bag and I swiped my card - what am I tipping for?

Sometimes it’s the checkout system doing this. In these situations I just hit no tip, because the restaurant owner will just keep that money for themselves, because there was no actual server who earned it. Sometimes owners pocket tips the servers do earn as well, but it’s less frequent because servers are more likely to notice.
