Tip question #1: In this instance, would you give the body shop owner a tip?

My car is in the body shop for some minor damage from an auto accident. I also go to the body shop once a year for my annual state auto inspection. I don’t use the shop for other repairs, as I get repairs and maintenance at the Honda dealer.

Since it’s the holiday season, when I pick my car up this week, should I give the body shop guy and his wife (who is the office worker) a bottle of liquor as a holiday tip “gift” or no gift?
