<human>: Can you give me the gist of the text in a nutshell?

Hello Reddit, this is my first post in TIFU and as with many other people's stories, this did not happen today. This happened a couple months ago and since then I have told the story to many friends. We all agreed it belongs here. 

Anyway, a couple months back I got off of work at around 10:00 PM and I was making my way home. I worked at a family friendly chain restaurant who specializes in bottomless french fries (hint hint). As an employee, these french fries are free to us during our shift. While they are delicious, they often do not fill me up with the protein I need. So after work I made my way to Taco Bell before going home. I was a car or two back from the window, so I do what everyone does and let a couple ones loose. It. Was. Not. Pretty. The cars in front of me moved through the line much quicker than I thought they would. Before I knew it I was parallel with the window and the unenthusiastic teenager was patiently waiting for me to roll down my window. So I told myself here goes nothing and roll down my window and hand him my money. He doesn't mention anything so I thought okay I am in the clear. He reaches out to hand me my change and pauses for a moment before saying, "Hey dude I think you have an exhaust leak I can smell it from here!" I nervously said "Oh okay thanks for letting me know, I will get that checked out."

To this day I do not know if I had an exhaust leak or not.
<bot>: Farted in the taco bell parking lot and it was so bad, the employee working the window thought my car had an exhaust leak
