Usually they ask about the delivery charge (with which I buy gas and which is therefore not a tip). I’m not sure who she thought the tip would otherwise go to.

That’s messed up! Everyone knows the drivers get a tip, just like a waiter would if you went OUT to eat.
Sadly, not everyone knows what Everyone Knows. I have been stiffed many times by people who assume the delivery charge is a tip.
Wow. Read through all of your comic in the space of a few hours. I think it’s very, very good. Definitely a productive use of my evening. I’m looking forward to future updates.
If PTBD causes an aversion to bacon, that’s horrifying.
Awww, thank you!
(I’m not at all averse to bacon, I’m just afraid to cook it again. Maybe if I invest in a pair of fireman’s gloves…)
