How strict is Empty Bottle about bringing original credit card to pick up tickets?

I bought tickets for a show at Empty Bottle. The tickets were in high demand, and in my rush to buy them I accidentally used my "virtual credit card" instead of my physical one. The virtual card has a completely different cc number but is tied to the same account. On the confirmation email I received, it says that you must bring the original credit card with you when picking up your tickets. I've checked my bank statements and while I have proof of the purchase, nothing in my bank account has the virtual credit card number listed anywhere so I'm not sure how to prove at the box office that I have tickets to the show I paid for.

Has anyone experienced something similar at Empty Bottle or another local venue? Would an ID and confirmation email be sufficient to get in? I'm worried that I will be denied entry due to paying with a non-physical card.
