odd thing happen to me tonight

I’ve been a cleaner for 10 years and tonight a member of staff comes into the lady’s loos and asked me why have i put a sign on the door saying..Cleaning In Progress Please Use The Disabled Toilets..and i said its because i’m doing a full clean shut down but she still kept asking me why until i said i’m gonna mop the man and woman loo floors soon and she said ok. my face looked like this >>> (O_O) because i’ve done the same thing for 10 years doing the shut down.

this is the last weekend for working for this company.
