i wish i hadnt done that

The biggest thing I have come to reget in the past few months is quitting my job at Cracker Barrel. Now, Cracker Barrel is the most god-awful place in the entire world to work, but I put up with it for almost two years just because I had developed a good relationship with my managers and co-workers and I made pretty decent money for working at a restaurant that doesn't serve any alcohol. One night about a month ago, I just snapped. I had been working 10-12 hour days for the past week, and they put me on a closing shift one Monday night. My manager (who is absolutely out of his mind and disappears for hours at a time when he is supposedly managing the restaurant) cut the floor down to just two servers at 8:30 pm (we dont close until 11.)
I felt like I was multitasking pretty well until we started to get our late night rush of bad tippers. I realized at some point that I had eight table while my co-worker only had two. When I asked him to take a table, he ignored me and went in the break room to smoke a cigarette. Then our grill cook let me know that we were out of meatloaf and chicken and dumplings. Now if you've ever been to Cracker Barrel, you know that those are about the only things that get ordered. I went to search for my manager and surprisingly, he was nowhere to be found. At that point, I had to leave; otherwise, I saw myself pouring a full pot of hot coffee all over the next customer who was rude to me and being involved in a major lawsuit. I calmly grabbed my keys and sunglasses, told the cashier that I was f-ing done with this place and walked out. That might not seem so bad in theory, but I had eight open tables, it was only 9:15 and there was only one other server in the restaurant.
Of course, as a result I lost my job for good, which is not exactly my regret because I had to quit that hellhole eventually. However, I regret that I lost my temper and acted out in such an immature manner. I destroyed everything I had built at my job over the past two years and pretty much ruined any chance of a good reference with just one little act. My regrets usually stem from an act of impulsiveness or flare-up in my already tempermental disposition. I say something or do something in the heat of the moment and almost immediately after kick myself for being so dumb. Looking back at my Cracker Barrel situation, there were so many other, probably more effective ways, to handle the situation. If only I was the type of person who thought things through maybe I would still be employed.
