I went to the refuelling.

The treasurer, with a learned voice, began to roar the duty phrases:

Do you want tea or coffee?

I have a standard joke about this, after which the sellers immediately lag behind:

I agree with Cognac. At least seven years.

But here the cashier immediately focused:

Unfortunately, we only have liquid for the glass washer from alcoholic beverages.

I continued to joke:

I usually eat cognac with lemon. What do you have under this drink?

I can offer an air refresher with the smell of lemon.

The gasoline payment ended and I had to leave. But the mood for the whole day rose from such jokes.
