For areas of the south I feel I know and understand the basics before I even step foot in the baitshop. Internet and magazines can help a lot in terms of getting ideas for what's going on and of course experience is number one in my book.

Likes: I like a clean unclutered store with stuff I recognize as good for the area Im fishing. Locally made baits are good as well since most of those are guys fish the area and could be making things to the fishes liking. I like to know if the water has been stable? Dropping? Weed choked areas? Shallow areas? Dangerous areas? If they want to toss in some fishing info that's great but I take it with a grain of salt.
Dislikes: pompous jerks who feel they are the man. Working in a bait store pays little and if they are not inviting me with open arms to spend money then I won't. I'll never ask for exact locations because I don't care. I don't care for stores that allow smoking (I know I know it's just nasty to me) I'll be in and out if I'm gagging to catch a breath. I don't like old plastics that should have been tossed 20 years ago. Im not a fan of walking into a store and having 10 locals sitting around the counter where I'm trying to look and do business. A few guys is cool but if I gotta take a number to talk to the owner or worker just to get a question answered I'll prolly leave quicker. I'm the customer and it's no different if I'm buying a car, food or at a bait shop. Treat me with respect and I'll prolly spend money......treat me like I'm bothering you by visiting your store and ill leave.
