Apple ID
Is it usual for an Apple employee to ask me about Apple ID & Password when I want to claim my iPAD ?

If you're picking it up at a store after purchasing it, then definitely not.
If you're picking it up from service, I'm less sure- but I still think almost certainly not. After the service has been carried out, there's no need for your credentials. According to this Apple page [Keep your Apple ID secure - Apple Support]-
Don’t share your Apple ID with other people, even family members...Never provide your password, security questions, verification codes, recovery key, or any other account security details to anyone else. Apple will never ask you for this information. [emphasis added]
It doesn't seem likely to me that they would need your account details, but perhaps someone else could weigh in on this issue?
