If I were taking advantage of their services, I would tip them too. As I’m benefiting from a first-world plate carrier’s service, I’ll tip them. Participating in a society by only doing things that help others when you might suffer consequences (via poor service on a return visit) is poor manners at the very least.

I don’t think this conversation is going to be very productive (at least on my end), so I’ll cut it off here. Have a good one.
