I have never seen such a lame service anywhere. Even in the most remote villages, people are able to communicate, unlike the individual who is in this boutique and, if I may say so, communicates (this is an understatement) with visitors.
It is a pity that there is no rating of "-51000000"
Send your staff to a course on "Good manners."
Judging by the reaction to the available comments in various search applications, the management "doesn't care" about the boutique.
