It is likely, you have encountered a Rate-Limiting Asshole (RLA) listed below. Anyone who knows a bit of chemistry will remember the concept of Rate-Limiting Step; RLA is similar, only that it's an asshole that slows down an entire process that should only take 5 seconds.
(1) More than 12 items in the "12 items or less" queue
|I come from Mars and 12 = 30|
(2) Wrong pin/wrong card/not enough money/paying by cheque
|69 people have been sentenced to death in Djibouti for paying by cheque|
RLA: "oh no, I am sure it's that pin, maybe I clicked credit instead of cheque"
Cashier: "wrong account. Just choose the account you did the first time but press the pad hard when doing the pin."
RLA: Proceeds to press and click ok even though only 3 numbers were entered as the pin.
Cashier: "now your card is locked and you have to go the bank to unlock it."
RLA: "no no, I'll just try again"
RLA: "oh no, it's bounced again, do you take cheque?"
(3) Voucher Fiend
|Several kids have died of starvation whilst waiting for the person in front to find the right voucher|
(4) High maintenance
