Why are Polo Shirts the first choice of business owners for their employees? Aren't Polo Shirts ugly and often filthy?

Why do small business owners and franchisees all across the USA require Polo-type shirts to be worn by their employees?

Of course they want something clearly identifiable to the customers , so they tell their employees to all wear Green Polos, or Red Polos, or whatever the choice is for that particular business entity. I understand the color uniformity… but why the hell is it always Polo type shirts? It’s a shirt that is made to never be buttoned up all the way, so why is that third button on it anyway? And that thick collar? Unless you wash it every single day, that thick collar is a source of filth, is it not?

Does anybody truly feel that Polos look better than clean pressed T-shirts? Or even a T-shirt that’s clean but not pressed?

I’ve never met someone who actually thought Polos look good… they just buy them, or require them, because they’re in a culture that somehow decided this is a casual-professional look.

But why?

What is it about the Polo Shirt? How did such an ugly shirt become such a standard thing all across the nation?

And isn’t the requirement of a “Polo Shirt” the first step towards fake customer-service, instead of true customer service?

Do customers really feel more cared for, or more clean, in a store full of Polo Shirt wearers?

Wouldn’t clean t-shirts look a lot better, and feel a lot cleaner, and make the place look more attractive than a bunch of those ugly Polos walking around?
