Whether you are expected to tip more depends on who you ask. The waiter, etc. will definitely say yes! But, tipping is supposed to be a voluntary recognition of superior service. Don't let other peoples' expectations affect your decision. In fact, old fashioned tipping was done so discreetly that no one else knew that money was changing hands. So, you decide whether you want to or not. If not, don't worry about it. Shake their hand and say thank you and let it go at that.
