need advice, do you tip apartment movers?

[wonderwes]

I am moving into a new apartment and decided to hire movers for the very first time. I just let them move the large items, the rest I would transport in my car. I dont have that much total stuff to be transported. So I have never hired movers before. I found a good moving company, but my question is do you tip the mover guys at the end of the day? If so, what percentage do you give them? Thanks.
