The pay flat out sucks. As a MT you are competiting with your boss for bonus. This is a conflict of interest. You should ask how many people as a manager has that store manager got promoted. You will put in at least 48 hours a week. Many locations are short of employees for a reason. On top of that you will have a to do a training program and prospect for new customers. You also have to fend off the other MTs for promotion. It is VERY competitive place. The working conditions suck. There is no heat and no air, so if it is 5 below or 110 above you get no break. The next step up is sales or management and still dog eat dog. While having very good buying power 84 does not get the deals that larger companies do, the materials are of slightly higher quality, but that makes sales tough. Expect that you will come in early on Saturday morning only to have managment go on a terror about lack of sales.
