Esso Extra

I stoped at this gas station today and started putting gas into my vehicle and my friend went to use the washroom. After i filled my car with gas then i wanted to use the washroom.

When i went there the cashier said to me that you cannot use the washroom. When i asked why then he said the same words that you cannot. I asked again and he said its out of service, which it was not. My friend just used it 2 min ago and he said it was working and is clean. Then i realized the person just cleaned the washroom and does not want anyone to use it as he might have to clean it after sometime.
They even sometime attach a fake paper saying out of service even when it is working properly. Most of the time after they clean it up.
