In transition: What was your first job and how terrible was it?

 As previously stated, I'm going to be beginning my new desk job July 4th. Until that wonderful date,  I am finishing up a four-summers-long career at Subway Restaurants as a "sandwich artist". Yes, that's right, I have been  performing fast-food customer service for four years! Is there any job that's worse? Well, actually I'm sure there are many (as someone like Mike Rowe could prove), but for me, 4 summers of working a dead-end job that I've always hated is pain and suffering enough for my lifetime thank you! The recent telling of my departure to my boss just reinforced this fact. Instead of wishing me congratulations on taking advantage of this great new opportunity, he was speechless with "nothing to say" apparently. He has ignored and avoided me since I told him and we have had no conversation on the topic since then. It is clear that he is an expert in passive bullying of the high school-girl type and I have been feeling guilty for some insane reason because of all this... In fact, I couldn't sleep last night because I had such a realistic nightmare of him canceling all my remaining shifts and telling me he was angry with me. (on a side note, he actually did cancel one of my shifts this week...coincidence?). But honestly, what do I have to feel guilty about? I gave him two weeks notice. He should understand that if an opportunity presents itself to me (a graduated university student) that is anything more prestigious than slapping meat on a bun, I'm going to take it! But anyway, I digress into another argument. For now, I will focus on a quick summary of my job and why it is so loathsome to me:   

1. Constant criticism - My boss has never said "good job" to me or any other employees really. Instead, there is always something to criticize.
2. Illegal slave labour - Employees do not have mandatory breaks and I have often worked a 7 hour shift with one 10 minute break or less.
3. Cheap, cheap, cheap! - My boss tells employees to save and stinge on everything we can, from condiments to veggies to the amount of cheese we put on the bread. He has one cleaning product for the entire store (which is such a failure against health checks) and he has made me return my previously used uniform at the end of every working summer. Any extra time employees spend working in the store (ie. that extra 10 minutes) is unpaid for. Finally, special deals/promotions are usually never done "at our location".
4. Customer Concern Garners Criticism- Health failures abound mainly from not properly washed containers (because everything must be done in a rapid fire motion and if you care about giving customers actually clean dishes, your boss yells at you for being slow). My concern with giving customers fresh, clean, good food is usually overridden as well by my boss`demands. The ends of tomatoes with the hard cores in them are saved because my boss is cheap and I always feel guilty giving these to customers to eat.

Well friends...that was my rampage on my first job. Do you have first jobs or just jobs you've hated as passionately? Or have you had good first job experiences? I'd love it if you shared your story with me!
