Requires A Nugget Of Sense

(This takes place at a well-known fried chicken restaurant. I have never had an issue placing this order, as the vast majority are aware of how to do maths.)

Me: “May I please get 20 chicken nuggets?”

Cashier: *who is definitely not a teenager; stares at me like I’m stupid* “We only do 10 maximum.”

Me: *after visibly steeling myself to refrain from replying sarcastically* “Then I will have two lots of ten nuggets, please.”

Cashier: “Oh! Sure! That’ll be [Price].”

(The sheer amount of idiocy shown was overwhelming. I was stunned.)
