Making wudhu in the shower

Q: I have just recently become baaligh. I have been performing all my salaah and have not missed any. However, I used to make "wudhu" while showering. One day, I realised that sometimes while showering I did not wash my face and make masah (faraaidh of wudhu). I cannot recall how many salaahs I have performed in this manner. Please advise what I should do.

Who is liable for damages incurred at a carwash?

Q: I own a carwash where I employ staff to wash the cars of customers who come to get their cars cleaned.

I erected a sign informing the customers that neither my staff nor I will be held liable for any damage caused to their vehicles on my premises, and entry is at their own risk. Is this permissible?

After making this declaration, if one of my staff accidentally damages a customer's car, who is responsible?
