So the SC is the tip? Different restaurants have different percentages?
To add on to what Carol posted, IF you ask about the SC, you open yourself to be being misled (that is putting it mildly) and being coerced into tipping another 15% or more. Nothing wrong with adding another 5% (totally your choice) on top of the SC IF you had service that you felt was worthy. IMHO, it is best not to ask about the SC.
