Should I give something else to the neighbors for helping with the snow?

We had a big snowstorm Monday into Tuesday, about 15 inches of snow. Tuesday (yesterday), my two neighbors came around with a snowblower and shovels and without being asked, they shoveled my walkway and used the snowblower to clean the driveway. One knocked on my door and told me to move my car so they could clean the area. As I walked to my car, I told one of them, “I’ll give you something when you’re done.” He said “absolutely not.”

I went in my house and got two bottles of wine that were gift wrapped, that were given to me as holiday gifts at work. I brought the bottles out and handed them to one of the guys, and told him “one for him, one for you.” I told him they were given to me as gifts at work.

My question is, should I get them restaurant gift cards in addition? At Costco, I can get $100 restaurant gift card for $80 (two cards with value of $50 each for $80). Was the wine enough or would the gift cards be a good thing?
