ice cream flavor paranoia

Today, when the store manager came out with the delivery order, some customers ordered 12 custard pans, 12 plum guavas and 12 Irish coffee...

We serve ice cream in 12 flavors at any time. Customers who place an order like this must be regular customers. They have eaten all our ice cream flavors, and they choose their favorite flavor without hesitation, and have no love for other flavors...

As for you, which of our ice cream flavors is your favourite?
