Reply To: Should I tell my manager?

Can’t give advice about whether to tell manager or not, but I would suggest you keep your hands busy, a cup of coffee in one hand, clipboard or notebook (and even a pen) in your other hand. There will nothing left for the clients to shake, lest you spill your coffee on them in your haste to organize yourself, LOL! Give a big smile and apologize on the spot for not being able to shake hands.
