I believe this is common practice, but asking is good. My buddy went to a shop years ago and when he dry fired the gun the guy behind the counter freaked out. He said he just set the gun down on the counter said I am sorry and backed out the door. I was not present for this and was just told about it after the fact… We don't frequent or even go to this shop anyways as I always felt the owners were very sketchy to begin with but some deals could be found from time to time. Plus when you just love guns you can't help but go in a place that sells them you know? But knowing what I know about the place I found it totally believable.
So yes always ask. While one employee may be good with it the next employee may not. However I think dry fire is a pretty normal practice before a purchase like all have stated here and would not be surprised to see it.
