That Eurasian that u refering to his not there and I know who's there and who's not, and I know who's the malay there and you are not talking to a 16years old kid here, I've been to Swee Lee since the early 80's.
So you are saying, I bring in the money and profits thus buying things from ur shop and u wanna teach the customer a lesson, Come on man , which world are u in. I come in ur shop and buying things from you and imagine u or ur salesman pretending not to know that I'm there, does that mean I'm as a customer need to go for courses. I don't even shout at them demanding something or a howlian demanding customer, I'm a normal customer walking in trying to buy something from that shop.
I think if you are running a business like that saying customers should attend courses, definitely you will close shop in no time, because all the customers feedback and inputs you dont even care and you are not trying to improve ur business by taking care of the customers.
For your info a foreigner or and angmo walk in there and this pityfull sales personal treat them like god, I saw that with my own eyes and I'm not bull shitting here, it's the fact.
Be realistic man, they are like that with a F---ing attitude, I know you and Swee Lee got good relation because of ur product review for their shop and most product that you reviewed are from Swee Lee so don't be bias here supporting them. I'm a customer and I know what kind of salesman Swee Lee got. I don't flame them if they really put in effort to at least entertain customers with respect especially locals like us Singaporean
