Working at Dairy Queen was one of the single worst experiences of my whole life.

I recognize that all DQs are different, management is different, all fast food restaurants have shitty management and I shouldn't be surprised, etc etc, but this was my experience working at Dairy Queen:
-First job
-Get yelled at on the first day for not knowing what ingredients go into what sandwiches (I had received no training up to this point)
-Get better after a few days, but then get yelled at for being too slow
-Go as fast as I can while still getting orders right
-Get yelled at for being too slow
-go as fast as physically possible, but my huge anxiety from being yelled at all the time and from idiotic situations* makes me screw up orders all the time
-proceed to get yelled at for screwing up orders
-after a couple of months, become better at job, but am stressed out to the point where I have to use breathing exercises for 20+ minutes before work to not have a panic attack because I dread the place so much
-at around the four-month mark, I get sick before work one morning, and throw up so hard I completely throw my back out to the point where I have to drag myself across the floor to my couch and can't get up after that
-Eventually I call work 45 minutes before my shift starts, I tell them I can't come in (this is the first time I've ever called in, BTW), manager screams at me "YOU KNOW THERE'S A TWO-HOUR CALL-IN POLICY"
-"Um I can't move"
-"WELL I'M JUST GONNA HAVE TO TELL THE OWNERS ABOUT THIS" (*slams phone*)
-I later bring in a doctor's note AND a chiropractor's note, chiropractor's note says I threw out my back so hard he thought I had been in a massive car accident
-get yelled at for calling in sick
-fast-forward, I haven't been put on the schedule for six weeks
-I walk in, get tired of it, quit on the spot and walk out

*There was a lot of dumb bullshit that happened at work, but the first example that comes to mind occurred when I was making two shrimp baskets; after I made the shrimp baskets one of the chunks of battered fat flew out of the fryer onto my hand. It immediately started sizzling and I pleaded with two nearby co-workers to take the baskets so I could get the fat off of my hand before I dropped them. The two co-workers just stood around talking to each other, and after I asked them to take the baskets they just looked at me then continued their conversation. I ended up having to walk out to the lobby and hand the baskets to the customer myself before I ran to the bathroom and washed the fat off of my hand. Still a scar on my hand from that. Again, I don't mean to generalize, but my experience with fast food (and fast food workers) consists of unfathomable douchebags and morons.

With that being said, I refused to even go near Dairy Queen because of the crap they put me through (and managed to convince my entire family and most of my friends to do so as well), but eventually I got over it when I found out the entire staff excluding the owners no longer worked there as of last year.

Their soft-serve ice cream is probably the best I can think of.

The blizzards at Dairy Queen are delicious, but I wish they didn't have like twelve trillion calories. I think Culver's probably has better ice cream, objectively speaking, but DQ is where I go when I want a conventional ice cream cone. As for Culver's burgers, I kind of have the same feelings towards them as I do towards McDonald's; any enjoyment I may derive from the taste is negated by the overwhelming stomach pain I feel when eating their food.
