Jokes around life

One day, a girl called the hotel I work for, "is the Managing director there called Jenny?" I said, Yes. ARE YOU JENNY? I said, No. ( Isn't jenny supposed to be a girl's/lady's name?)

Another girl called. Do you have a vacancy tonight? I said NO, we are fully booked. " Perfect, bye!" She said. (What does perfect mean? Madam?)

A lady called. Can I check avaliability with you? I said, " YES. On which day, please?"
' Oh,' she said, ' Can I call you back about that?' (what did she think about before calling?)
