Service Attitude?

I have been pissed off on last sat. After my drench of rain, my mood is not gd. I went to Raffles City for shopping with baby.
Decided to go into one of e shops with a horse logo got even pissed off. One of e sales assistant was looking at me from head to toe to see if I could afford. In chinese, it means da liang which I hate. Obviously he thinks tat I cant afford to buy anything, he went to aside n do his own things. Throughout our 15 mins or even more in the shop, no sales assistant wants to bother abt us. If I am not wrong, I even heard of e staff saying tat I am not going to bother abt them! Hello, do I have to wear Burberry Polo-shirt, Levi Jeans, carrying Gucci or Levi bag or even shoes before anyone could serve me? This is the kind of 'gd service' attitude tat I am supposed to have?
Went to e hotel in e shopping centre, which is a 5 star! Obviously I found e same service attitude as mentioned above in e same day! They decided to da liang me again n use a irritaing voice to reply my question.
It makes me wonder how a 5 star hotel or branded shop got their good service from? From e foreigners or tai tais whom they will serve diligently?
If for every customer who goes into e shop, they decided to da liang, they will lose out tons of potential buyers. I suppose no one will place their cash on their hands n tell everyone tat they r rich or they r going to buy something? Some buyers like me will go into e shop n see wat suit them n go back later to purchase it.
Come on, who will go into every shop n buy things? They think tat ppl print cash?
Shall stop here before my list goes on abt bad service attitude. wahaha
