There are too many statements to quote here so I'll tie it all in to one answer........
Glass cases? Well, think about it this way - Lets say the bags are out so you can touch them. Great! Your an honest person who has no intention of stealing. But here comes "Betty" who has absolutely NO intention of paying for a bag and sees nothing detering her from taking it. There goes the bag. Loss to the company, higher cost for you and I in addition to the already sometimes RIDICULOUS markups.
Why don't sales associates chase after thieves? Safety. Plain and simple. If a person is brass enough to steal, then what makes anyone think they may not be brass enough to physically hurt someone that tries to stop them from their crime?
Don't the stores have LP? Of course. Think about this though......In a dept. store, you have how many depts? Womens, Men's, Jr's, Children's, accessories, intimates, home, jewerly, shoes, fragrance and some of those have multiple sub-depts. Ex. women's has collection, moderate priced appareal and sportswear in some cases. Not to mention some dept stores have multiple floors. Each dept isn't going to have only one camera on one section so you'll have multiple cams in each section and sub-section...........A large dept store has approx. 3-5 LP agents who watch anywhere from 20-50 screens (this told to me by friends I have in retail) to ensure the merchandise is purchased not stolen. Now, how are 3-5 people going to watch several different depts at once and if there is a potential thief, go out into the store to watch and possibly apprehend them? Yes, they should probably hire more LP agents but that doesn't seem to be the reality in today's economy.
For me, an inconvience yes, but I don't mind it as most SA's I've encountered are happy to assist me.
