I stick with the tipping habits I grew up with.

• If I'm getting table service at a restaurant, I tip the waitstaff.

• If I'm getting food delivered, I tip the delivery person.

• I tip taxi drivers.

• I tip bartenders. I'm honestly not sure how to tip bartenders these days though, because it used to be "$1 per drink", which seemed quite generous when drinks were less than $5. Now a single drink might be $12. Am I really supposed to tip 20% on that?

If I'm walking up to a counter and getting takeout or fast food, I'm not tipping. That's nutty. Nobody would even consider that if they didn't use these customer-facing tablets everywhere nowadays.

Sometimes I'll toss a buck in the tip jar at my favorite coffee shop or pizzeria, but it's not a percentage thing.

I've always known old people to be shitty tippers. Maybe I'm on my way to becoming one of them now, failing to keep up with social norms. But I really don't think this is the norm, and I don't want it to become the norm.
