One last comment........I've taken the time to actually figure it out and 20% of $70 is $84. U saved $16?????
WOW!!!!  Instead you agreed to give him your $30 in small bills and dropped the rest off later?  I've RARELY commented on this board, but this put me over the edge!!  I guess I'll overtip next time just to make up for people like u.  Not much shocks me on this board, but this does.  It's almost funny!!!
