Once i was at Tsen Lighting, their Bangla staff want to sell to another foreigner discount 30%, then the lady supervisor whack the Bangla infront of customer, say max only 20%, please lah if want to whack go behind, don't do it in front of customers. The lady supervisor always sit at counter, want to pay also her muka masam. The Chinese guy worst, very lazy, you ask only he answer, like not keen to do business.
