One of the good day with my crazy friends

My friends sometimes are strange... In this day, we went to McDonald. We ate our "dinner" but we didn't have lot of money so we didn't buy any drink. Only one for us had some money and he bought cola. When he drank his drink, we went to KFC with cup from McDonald. There my three friends pour drink to the cup from McDonald and they bring this drink to us. When we drank this, my reckless friends again want to do the same. When they were trying do this the bodyguard approached to their and took they to the "room service". I and my one friend was careful and we didn't catch by this bodyguard ;)
I don't know why but I and my friends always remember this action and we always laugh ;3

Can you comment this if you understand anything? I'm from Poland and I don't know what I'm doing wrong.

Thank you so much :3
