Eeek, that sounds extremely sketchy..Sounds like you had a better experience then i did a few weeks ago. I walked in and 3 very interesting looking rough guys in there late 20s all tatted up and gauged up were having their "girlfriend" buy them a gun. I knew because she kept asking what kind of ammo do you want? and do you want any holsters? "I don't care I wont be shooting it" and the gander people just kept running the paper work for her. I mentioned it to one of the sales clerks and he said "that really isn't any of our business"....I left immediately.
As for Gander's, sounds like it's hit or miss with a lot of people.. with a few more misses (heh). I've heard a lot of bad things about them, from the staff to the high prices. Kinda makes me glad there's a Cabela's near me, and not a Gander . Cabela's can be high priced as well, but the staff is generally very friendly and always willing to help, with no attitudes (and YMMV). I know the gun counter at Cabela's is pretty much the same though, with a bunch of people at the counter and only 2-3 people behind it, trying to attend to everyone.. especially in the evenings when people are getting off work. You can be waiting there for a little while 'til someone gets to you or even greets you. That usually doesn't bother me too much though (I know they're busy), unless I end up waiting a ridiculous amount of time or they help someone else first, who came up after I did.
I always think they could use more help behind the counter in the evenings and on the weekends, reguardless.
