atari 2600's post is depressingly truthful, and not just for fast-food restaurants either, but basically anywhere where the chances of promotion or advancement of any sort are basically zilch, and where you slave until you earn senoir citizen benefits and get paid
exactly the same amount of money back when you started out as an 11 year old fresh from the home for juvenile delinquents and troubled youth; e.g factories, convenience stores, video stores, etc, etc. The truth of the matter is, these places are only good for people who have failed in some capacity in a position of some responsibility or authority elsewhere; for these type of people, the situation is ideal, the whole 'big fish in a small pond' archetype fitting these people to a 't'. So, they have a chance to 'redeem' themselves by exercising every iota of power and authority they have; and they do so by taking it out on all the miserable and desperate people aforementioned in atari 2600's post. The best bet is to get out of there while you still can; find a job that makes you practice your skills, either mental or physical. A job in a workshop is good, though hard; it is the type of work atmosphere where your contributions are easily recognized, construction work is also tough, but good, as the pay is reasonable and the work affords you skills that are hard to come by. I'm sure there are tons of jobs out there just waiting to be discovered. Do not trap yourself in a dead-end situation.
