We don't need to understand why, because they don't understand we don't we 😂
Once I purchased a very good quality brandless t-shirt at Hat Yai. The store operator won't let go for anything less than 150 Bhat, since I know my shit, I agreed and took it. Well, my buddy was the one saying, he don't understand how would I pay such a premium for a no brand shirt 🤣
Oh that t-shirt I'm still wearing until today, since 2016. So, technically I know my shit... Shirt I mean.
That is a very cheap price for a shirt but if it was at a market in Hat Yai, that is understandable. As far as brands are concerned in Thailand, unless you are in a shopping mall at that brand's store, you are almost certainly getting an illegal knockoff of the shirt anyway and well, it is probably exactly the same material.
