Hello, this will be my first time going to an Oakley store. The one I plan on going to is an oakley vault an hour away which is the nearest one. I have always brought my oakleys at a sunglass hut where the sunglasses are not locked up and you can try on the sunglasses without asking for an employee to open them. Is the same procedure the same at an oakley vault? Are the sunglasses locked up or open where you can just try them on without asking someone? What is the etiquette when buying oakleys? How many can you try on? Will they get mad if you try on several and not like them and leave? How many people work at a oakley store because the sun glass hut I went to had only one employee and it was the cashier.
