Sana walang magagalit but I think sometimes yan ang problema sa ugali ng Pinoy, may pagka-insecure. Tao lang naman ang mga sales agents and they also need to make a living just like us.
Sa mata ng SA, di naman nila tayo kilala and the first impression they will get is how we dress up. But what will matter even more is how we treat the SA's. And there's no shame in saying up front if we are just looking around or not ready to buy.
Anyway, from personal experience, kahit gaano ka simple ang suot and kahit gaano ka high end ang showroom, I've never encountered an unfriendly sales agent. Minsan nakikipark pa nga ako sa BGC showrooms like Lexus or VW if say I need to buy something next door quickly.
