I have infinite weed responses for this, but haven't seen an upper/bender-related story yet, so:

Was on what was probably my most drastic, sleep-deprived bender of my life: a week-long adderall bender (getting a few hours of sleep here and there) studying for finals, and was on my way to a final, having not slept the night before. Hadn't eaten in a while, considering the bender, and had no time to eat anything good, so I decide to stop at Mickey Ds quick before my test for a couple McDoubles.

So I get to the register, and order 2 McDoubles, no ketchup--my usual order. The very-english-impaired, latin cashier tells me, something along the lines of "sorry sir, no McDoubles", but I couldn't really make out what she said, and it was unfathomable to me that they wouldn't have McDoubles (what I get every single time). So I order them again, and she responds again "no McDoubles", a little irritated this time (probably because my response to her first denial was a bit annoyed). So i say "alright, lemme just get 2 McChickens then". Now, she looks at me even more confused, and says "sir, no McChickens", with a few other words in there. I look around the place, kind of trying to figure out where the fuck am I right now? McDonald's doesn't have McDoubles or McChickens? So I look at the menu, confirm that the 2 for $3 McChicken deal is still going on, and say something like "Look, I just want the 2 for 3 McChickens".

It was at that point that the cashier, in what was her best attempt at pissed-off English, told me "Sir, its 9:30 (am), we only have breakfast right now."

I didn't go back to that McDonald's for like 6 months.

TL;DR I had no idea what time it was and didn't understand why I couldn't get a goddamn McDouble (no ketchup).
