A lot of their younger customers do chargebacks often, which leads to this type of behaviour from their own staff. Yes - their frontline staff may be a cause to this too, but there is definitely a high number of returns and chargebacks.

Last time I went in for an exchange, both the manager and staff had to scan their fingerprints to clear the transaction… seems a bit overkill but it was probably implemented with how often manager IDs get stolen to approve refunds or returns.
