Joined a group of friends who had settled on the terrace of this cafe / brewery.
I was very surprised to find that by entering the restaurant and crossing the corridor to go to the courtyard where my friends were present, strictly no waiter said hello to me while they saw me all in turn but obviously too much in the "rush" ... Anyway.
I moved to the table where my friends had finished dinner. I was about to order something to nibble and drink when a waiter came to our table (6) and said "good evening" from the other end of the table.
I will return him good evening.
But that's when he said goodnight again looking at me insistently ... I let him know that I have already answered .. and I turn "no but you looked astonished that I say good night" with a provocative and naughty way ...
NEVER SEEN, even in the PMU of the corner the server does not have this behavior ..
But I tell myself that he was probably tackled by his girlfriend tonight .. What would be normal seen his mouth.
So, I gave up eating at home, even a glass of water from their tap.
I will not come back !
