I don't give a wine with every thank you but those who have done something very special for us or do a fantastic job do get a wine from us. When the cable guy came to install the cable box for my daughter when she moved back with us went out of his to fix some other problems we had, he got a bottle. The guy who takes care of our vehicles gets a bottle, good mechanics are hard to fine.
Lol, I have a new puppy in the house, she is adorable but she chewed the cord on my computer so I asked the tech at work if we still had any of those cords and he said he had a box of them, he brought one down to my house after work, he got a bottle of wine.
Yes when you have someone who does a great job, they deserve an extra "thank you"
