How can I drink 15 coffees when only 14 can gift them to me?

There is a PROBLEM with their system that needs fixing. Currently, if your whole team drinks, then you will get 14 drinks max the first day, and your timer will read, "Drunk: 14/15" This won't reset to 0/15 until 24 hrs after you've drank your first drink. Yet, you can give drinks every 23 hrs. So, if someone serves before your 24 hrs drinking timer is up, you will get 15/15 drinks. But it is a TRAP! Once it reaches 15/15, all the drinks in the cafe will disappear and the timer will say you can't drink until your 24 hrs is up. But the drinks that had been served in the cafe will NOT return. The SOLUTION is to not let the timer reach 15/15. Instead, wait until your timer says "0/15" before your drink. This means your ability to drink will get later and later every day until you skip a day or the developers fix this issue.
