Questions & Answers about בקופה ביקשו ממני תעודת זהות וכרטיס אשראי.
Here בקופה means at the checkout / at the cashier / at the register.
The basic noun is קוּפָה. Depending on context, it can mean things like:
- checkout counter
- cash register
- ticket office / box office
So in this sentence, it refers to the place where payment or verification happens.
ביקשו is 3rd person plural past: they asked / they requested.
Hebrew often uses plural verbs with no stated subject to mean something like:
- they asked me
- someone there asked me
- the staff asked me
This is very common when the exact person is not important.
So ביקשו ממני does not necessarily mean several specific people literally asked; it can work like an impersonal they in English.
