Me, either. I pay for service beyond the food I’m getting, and with takeout, there is no such service.
It would never have occurred to me to tip for takeout either. Once in awhile you see the tip jar at the take out counter and I’ve always thought that a bit gauche. Always assumed the chef/cook placed the food in the containers for some reason so why would I “tip” the person taking my money lol. But 75 orders is quite a lot. The restaurant could have offered a discount for that, then what’s left over could have gone to the waitresses that packaged everything up.
