I went this morning at 11am. I settled in heated terrace. A server where the boss comes to me. I say "hello sir". He does not say hello. Just one: what do you want? A coffee please. At the moment of paying: he breaks me the saucer on the table with not even a thank you and goodbye. I pay and I leave immediately. There was no one at the terrace and inside only 2 customers at the counter brief it was not in full rush of work which could have justified or mitigate his lack of courtesy. A star on 5 stars is already a generous score!
