Given the high price tags on the glasses, you would think staff would enthusiastically greet new customers when they entered the store. Ahhh ... that is not the case. More like an icy reception.
Forget about trying on glasses yourself. Every single pair of glasses is locked on the open displays and behind locked glass sliding doors.
Since I did not want to deal with hovering, unfriendly staff while trying on glasses, I opted to leave the store and take my business elsewhere.
