@_josephine0_ The math is off. Don't short changing yourself...
10% of $92.50= $9.50. 5% of $9.50 is $4.75 + $9.50 = $14.25 X 4 = $57.00 - that's 15%...
Wait service is hard work; 15% has been the tip base since before the 1930s. Accepting less is a crime.
@Jassmini2 None... no one would dare breath a word about themselves in that way. The unwritten demi-law was conformity at all costs. Fit in, blend in -- be in!
