Customer disservice

I thought twice about posting this, because if it weren't me, it might appear as quite mundane. What the heck, I'll write about it.

I went to "an office" and was directed "upstairs". Gosh, the lift was quite slow. I exited, and asked the unfortunate woman walking rushedly down the aisle, where the department was that I was seeking.

Eventually, I reached it, and (rhetorical questions get you far) I asked if this was the department I was looking for. It was an unspoken "yes". How do I know? The lady on the counter whom I asked, who was closest to me when I approached for assistance, "looked at" her colleague farther away, and he gave the approval: "YOU DEAL WITH HER, IT'S OK".

(You'd need some cultural understanding to get the scene and language I've referred to)

How does one deal with such experiences? Does there come a time when you shut your eyes or speak your mind? Which is better, and why?

I figured the Indian guy and Egyptian lady who chose to serve me (nationalities are not important, are they) are probably not happy in their jobs, but for one second, they should step out of their shoes and understand if they were in my shoes, they would probably not want to be treated in the way they treated me.

This time, I kept my mouth shut, knowing "what goes around, comes around".
