I sprinted ahead of an old man for ordering coffee and he told me I was a jerk. I said 'Yes sir, I am but way worst is coming to you' and the staff smiled. Turht is, he also did not want to wait and I bet he took 10 minutes for ordering his coffee. So I think maybe God was telling me I am certainly not perfect. But it was kind of fun to be rude without anyone being angry or impolite truly except for walking ahead of him. Old people have to get used to it.
