What happens is that the clerk is constantly being asked the same questions over and over again. It goes with the job. I was told by a clerk once that you see guys come into the shop, want to know what is hatching and buy nothing. Ever notice when you buy something at a shop the information flows. That's why some shops have a blackboard outside the shop with the hatches written on it.
I had a chance to work partime in a fly shop but decided it wasn't for me.
It's a service business it that simple. On top of that the clerk has to work on the weekend when everyone is fishing. Just my observations. FishHawk
