Have you ever walked by a customer and let out a silent but deadly by them? I have atleast 8 different times and it's great to watch their reaction to those hot fart smells. Really puts a smile on my face.
I usually don't by customers, but I do by my coworkers and p*** them off. I just laugh at them My supervisor has sprayed me with air freshener a couple times because mine are so bad lol.
