I experienced that numerous times already but I always end up entering the mall. How? Do one thing, go to the entrance near the Virgin store and when the guards will stop you. Just explain to them that you came from the other gate and you need to give them reasons(I often use these two and it never fails)1. that I need to go to the pharmacy to buy cough syrup(do the sound effects ok?) 2. I will pay my credit card bill in CBQ which is due today.
Tell them also that the guards from the other gate told you that you can come in through this gate and assure them that you will not stay long inside.

In these situations, we need to improvise and be confident with ourselves. The kind of system they implement sucks. The capacity of a person to purchase goods does not lie on his RACE.
Enjoy shopping!
