So we were meeting with a group of customers in the morning and we wanted to bring doughnuts to the meeting. Unfortunately, one of the customers was NASA, so we couldn't bring doughnuts to the meeting because that would have been too much of a gift/bribe.

The rules for rank and file employees already exist, it's the ones at the top that can flout the rules that are an issue.

If it may be involved with or adjacent to the work they are doing, I would say yes.
