The problem is technophobes like you are just not tech savy enough to use a freezer. It's really quite simple. You just two finger tap on the product you want. Use the biometric thumb print scanner to determine which discounts you currently qualify for. Select "quantity available" from all the options. Watch a brief five minute targeted ad informing you about all the new vaccines and booster available to you. Then you would have seen that there were no more available and would need to repeat the process for the next desired drink. Looking though a transparent door to determine the quantity available with identifying yourself and providing the store with valuable ad revenue is basically shop lifting and should be prosecuted as such.
