Customer: “Where are the escalators and lifts?”

Me: “Sorry, ma’am. The lift is reserved for people who are unable to use the stairs, and there are no escalators. There is a staircase just over there, if that’s what you’re looking for”.

Customer: “But those are ‘down’ stairs. I need to go back up.”

Me: “Ma’am, stairs go both up and down. That is why we have stairs instead of escalators.”

Customer: “But I need to go upstairs, and you do don’t have any ‘up’ stairs. Are you trying to trap people here?”

Me: “You know what? Let me show you the lift”.
