Diadora HK Ltd - Hong Kong

I dropped in your outlet at Olympian City II today afternoon after seeing a large promotion board with the words "EXCISIVELY PREMIUM". I told the young man on duty that there is a spelling mistake found on the promotional message. The letter "l" should read "L". The young man said nothing and just turned away from me. I do not think this is a good manner and hospitality that a salesperson of a renowned company like Diadora should perform to a customer who pointed out the mistake to the company with a good will.
