Almost everyone pre-judges and puts everyone they see in a little box. I, too, dress down for large purchases but not for fun. I do it because when you are dressed nice and the salesperson has the ability to drop a price; they are less inclined to do so if you appear to have money.........not always but mostly. As a consumer, you have your own priorities and what you look like doesn't answer that. This could be: price, service, ambiance, availability and some people just want their rears kissed and make people feel like trash whether you care to admit it or not.
A good salesperson can take care of everyone by asking questions to establish these priorities and then CLOSE THEM. They can associate and comfortably speak to anyone and make everyone feel like they are the star; regardless of how many customers they have to deal with. I think you are asking a lot if you are expecting to always see a rock star salesperson at a retail store making $8-10/hr with crap commission.......maybe. It's like asking the fry guy at Mickey Dee's to make you a perfect risotto. I am not saying they cannot do it, just that I wouldn't expect it. As a salesperson and a consumer, I make my own judgement as well and if I walk into a blank store front with cheap furniture, floors, decoration......basically a low-end store; my expectations are low. If I walk into the Altsmoke pictures I saw in this thread, I would expect higher end service and better salespeople. Whether I buy from them or not is determined on whether they meet those expectations. For me, I at least expect the salesperson to know what they are talking about and a price that isn't twice as much or more than what I can buy it from elsewhere. This makes vape stores unique because it is one of the few industries you can circumvent the retail store by buying direct.
To the OP's point, I have been in the type of vape store they speak of. It isn't customers that I am being ignored for, I could accept that; it is a collection of like 10 of the sales staff's friends.........that are just talking and hanging out. If I did get attention, it was as rushed as possible so that they could get back to the conversation they were having about this twisted, super barrel, 2 wrap micro-nano-mini coil that they got .002 ohms on. Actually, it wasn't until I happened in that store one day with my Provari and a Kayfun that they acknowledged my presence and now when I go in, I get GREAT service.........every time.
The irony behind all of that is the store owner has 6 people working in a store front and adding to the retail space, adding a pro-shop, bar, big screen, Playstation 4 and their prices are 3-4 times what I can buy it from online, probably due to the owner's overhead. That doesn't sound like smart business to me. Even though they sell the Provari, I wouldn't buy it there and I don't make large purchases there so honestly, their original lack of service was pretty warranted............or is their original lack of service the reason I wouldn't make a large purchase there?
