We have basically stopped going places that would be tipping situations. We don't do doordash or any of that other lazy crap, so can't comment on it. My basic understanding is ipay a delivery fee for it, so I wouldn't tip them, as I already paid for the delivery to their employers. If they were to like, sweep up my patio or something out of expectations, then sure, but not for just doing the job they're hired for.
If we go somewhere for rinks, a dollar per drink is still our standard. Unless you're just handing me a bottle or can, then it's less.
I don't tip take out. I came and did the work. Unless you go above and beyond somehow, I paid for my food which was the only service rendered. I see no reason to tip for that, I don't tip when I buy stuff at the store why would I tip for take out? Caveat, sometimes at mom and pop locations or family run places, I will tip. But not a chain restaurant or larger restaurant.
In the limited times we go out to a sit down restaurant, I still tip 15 to 20%. I think we have been edging lower as service has been declining and more places are changing over to electronic order taking.
Frankly, I think interacting with servers is the worst part of eating out, so I look forward to them all being replaced by touchscreens. Servers work half as hard as fast food workers and expec triple the pay.
