heres how i ordered my last two grinders:
"can i get a cheap ass blue grinder please"

or ( whilst wankered )

"can i have a grinder?"
"sure, which one?"
"i dont care, *hands over wallet*"

Luckily the next day i noticed i had a blue £5 one that to this day works flawlessly.

buying these things stoned just seems to work out better for me..
