Client: (yelling) what took you so long? It’s 12:51!

Me: I thought you said to arrive at 12:55p.

Client: (yelling) Young man… Don’t you ever dare talking back to a client! If we say 12:55, EVERYONE knows you need to be there at 12:45.

Me: I apologize for my lack of understanding, I’m just trying to meet your expectations. So, for future reference, you want me there ten minutes early to the decided time - 

Client: (yelling) No, be there on time!
