I have a few vendors I work with every day, and I couldn't run my business without them. Electrician, plumber, transportation vendors... I give all of them a big tip for the holidays!

I was wondering if this is a common thing - it is in my current industry, where I see my vendors every day. But when I lived in America, I never saw most of my vendors (they were mostly online, like my web hosting company) and so it never occurred to me.

Do you give vendors at work a holiday/Christmas tip?
