People get way too bent outta shape over being given the wrong size drink. I can't be expected to hear a pig fart through that drive-thru speaker, even if someone plastered the pig's ass against it, OK? It sounds like ZZZZTZZZT-ra LARGE PEPSI-ZZZT-BZZZZZZZZZZZZZ makes me want to stab myself in the face with a plastic spoon ZZZZZZSSSSSSSTTTTstaticZZSST.
So ya got a large drink instead of an extra large? Big deal. Learn to pronunciate or talk louder, dammit. You think someone would figure that out after I say "WHAT?!" fifty billion friggin' times.
