Is it inappropriate to hug a utility worker?

After being without power for three and a half days, it was a magical experience to watch the electric line being reconnected to my house. I'm too shy to go through with it, but the urge to hug them was rather strong. I also thought about offering pie. But they were hard at work on the neighbor's house.

We didn't have 100 mph wind in our area. The local airport only recorded sustained straight-line (i.e. not a tornado) winds of 94 mph.

We've lost at least three large trees, none of which are on the ground where we could take care of them ourselves. Even after what I'm sure have been some very long days, everyone we've talked to at the tree services has been amazingly friendly (though unfortunately not available for at least two weeks). Ditto for the customer service agents and onsite workers for the utility company.

And my neighbors - we'd be in much more serious straights without their generous and skilled help over the past few days. We are so fortunate to live in a community with such wonderful people.
