Dear god, why. O_O
I never made crazy fast food orders, but a few years ago my friends and I would troll drive-thru's (not at the expense of the worker).
My highlight moment was ordering an ice cream cone, pulling up in a cowboy hat, and flirting with the girl in a very awkward way.
"Hey... do you like my hat?"
"My hat, how much do you like it?"
"It's a nice hat..."
"Yeah, yeah it is, isn't it? I bet you want to know what this hat is for."
I get my ice cream.
"This hat is where I keep my cream."
"My cream. I keep my cream in my hat. Will you help me put my cream in it?"
I then put the cone, ice cream and all, into the hat, put the hat back on and looked at the lady who was now cracking up hysterically.
"I'll be back for more, sweetie."
Was not worth spending the rest of my night with ice cream in my hair.
