So like the accountant filing your taxes, the person who fixes your bug in the bug report, the electrician adding power to a new room, the plumber fixing a leak?

It definitely feels like an abdication of responsibility (and obligations) of the company that those people work for.
Nurses don't get tips but it's very common for them to get thank-you gifts and treats.
