What are the odds?

What are the odds of walking through an indoor breezeway with one other person and looking out the window and seeing a large group of landscapers working in uniform. They are all wearing brown shorts and a dark tan shirt. You say to the person you are walking with (and the only person within 1000 feet of you) that they look like a group of UPS workers because of said uniform. What are the odds of hearing a voice directly behind you say "But I am not mexican" and turning around to a UPS worker who came out of nowhere and was walking directly behind you ?? Seriously? Only me.
