All the best sir. Yes you're right, I would be worrying about them as well. Our parents always told us / remind us - don't take stranger's things, don't help them look after bags / baggage at the airport and don't take anything the stranger gives. Even they tell you ( the kids) I'm your father's / mother's friend etc. Don't and No all the best sir 👍🏻 can't wait for you to get back home after all
