Gas station mananger called the cops on me (details)?

About half an hour ago I went into a gas station to buy some black'n'milds (cigarillos) and some cigarettes. I asked for wood tipped, and as soon as i got outside i noticed they were plastic tipped.. I went back inside to ask if i could get the wood tipped ones, and just as the clerk was about to do the exchange (same price) the feminist dike manager (pardon me) stepped in and said she couldn't exchange them.. I said "well I just asked for wood tipped ones, so I should get the items I just payed my own money for".. she started saying all this bs about how they can't exchange, and that the clerk was new.. I told her - just because the clerk is new, I can't get the items I requested, and paid for?.. I walked 2 feet out the door before realizing,, she said it was MY fault for not inspecting them when handed to me to see if they were wood tipped.. (..so I if I bought 100 different items and walked out the door and noticed they werent what I paid for, it's MY fault for not inspecting each single item?) i had the receipt and all.. Just because she's a new cashier and doesn't know what she's doing, it's all my fault? I was arguing with this dumb manager of the gas station who seemed to not like me, and even the clerks were on my side.. she eventually called the cops.. It's not the amount or value of what "I" payed for, it's the principle.. I told her I have exchanged plastic tipped black'n'milds for wood tipped ones a couple times from a cashier who got confused, and asked her what that girls name was - she wouldn't give it to me, I told her i need her name to report this store for conducting "illegal" activity numerous times.. she said she isn't authorized to do that.. i shook the nice clerks hands they were cool and were on my side, the manager was a b****.. Don't know why I'm writing this, im just a little irritated, i should have waited for the cops, so i could tell them. she even tried apologizing to me and stuff cus she didnt know what the hell she was talking about and just wanted me out of the store.. i just wanted to prove a point. i was being polite and everything. i want to get what i pay for :( ... useless question, and over such a small thing, but it really irritated me.. what's the deal with this? lol
