I've been 3 times for the same thing, 2 times the same boy has treated me and treated me badly. I ask for some cases for iPad 11 and he gave them badly by showing him the product he wanted in a printed capture and being for a customer so he wasted my time mid-morning. The last one was attended by another boy and gave me a final solution.
Very friendly both but the first one should know their products better.
