I just hate Monday

Damn it, nothing great is always happening on Monday. Went to work at 8 and i got gl-ed by a customer. Fucking think he very intelligent, know or the things, but in the end he is just a loser. Served him the oreo milkshake and he commented that the cup changed to so small, like scam, cheat his money, then i told him, we just changed the cup but the amount is still the same. He said where got same, the last one looks bigger and this one is so small. I told him again, its the same its just that the older glass looks bigger. He said, what bigger, you dont try to insult my intelligent, you think i am stupid or what. I insist that its still the same, and he continued saying next time whatever i say just say ok dont try to talk so much and fucking hell i just said ok and turn away. Then he asked another staff saying he want to see the manager, then jalex went over with both the old and the new glass with water inside. When he went there the guy asked him who are you. Jalex dont care just say actually its the same and pour for him to see, then he nothing to say, say maybe its his mistakes. Fuck his mother whole family die, tmnnd. Trying to act smart but not smart, not youngster somemore. Looks like 30+ already still so stupid. Still dare to say dont insult his intelligent, in the first place he got or not. Fucking hell, spoils my mood for the day.
