I see tremendous variation in gift policies, year-round. I go to a conference at which some attendees sometimes buy a round of golf at a nearby club for whoever's interested. Clearly not a bribe, since anyone who knows the host is welcome to join in, but a very expensive gift, and perhaps something that might associate the host with happier vibe than their competitors. The golf-loving government workers grit their teeth and decline. A lot of the private sector workers accept the invitation.
Various government agencies set dollar amount limits on gifts. For us it's $25 or "ordinary business lunch". For others it's $2.99. For others, they can't accept so much as a pencil with the company logo on it. So I have a collection of ballcaps, squishy toys, mugs, and travel alarms. On the other hand I'm not allowed to let anyone cover my airfare to visit their facility, give me a ride in their company airplane (even if we're both headed to the same place), or comp me a hotel room. I have a friend who works for a company we do business with, and I can never accept his offers of the extra room in his hotel suite. I've met other people who can't accept offers of a cheap breakfast.
We used to get Christmas gifts in the office here--a box of pecans, a giant chocolate bar. Polite word was sent back to the givers that we really can't accept those, and they've stopped.
Then there's "ordinary business lunch". A lot of us take the view that if our employers (who include the taxpaying public) think that we can be bought with a steak, then we really shouldn't be on the payroll at all, and we interpret the provision pretty loosely. Others in the same agency won't accept lunch as a matter of principle. If the shop foreman buys our inspector lunch on a daily basis, though, that's seen as a problem. If the inspector comes to start expecting daily lunch, that's a bigger problem.
But the thing is, we worry about gifts and the perception thereof. It's harder to control human relationships, and tough to say how much that should be controlled. I go to conferences and work on committees with all kinds of people who my agency might do business with. If we're normal human beings, after a while some of us will make friends. Now what? To me that's a stronger factor than any fancy dinner or round of golf. And that's where the salesfolk are smart. It's not so much the gifts they hand out--it's the personal relationships they build. Good technical salespople will do what they can to make themselves your first point of contact when you have a question about their industry. They'll be people you're glad to see when you run into each other. And there's no way to regulate that. Even if you could, people change roles--someone moves from private sector to public, and they need to sever their social ties from their old job? Can one tell when someone is being friendly and when they are, in essence, prostituting themselves?
Tough stuff.
