I saw quite a few foreigners (probably foreign workers) visit them. I'm sure their profit margin for screen protectors is quite high.
I'm sure you all have heard about those $10 or $19.90 screen protector which they market to be very good etc. and because most people who visit need help to apply the screen protector, the shop (not specifically saying p2o but generally some ahbeng shop) sometimes secretly swap under the table to a cheap one (which doesn't even have oleophobic coating)
Many of these customers don't even know the brand of the screen protector applied on their phone since the shop often just throw away the packaging without informing the customer.
