A question for those of you who have a contract with a caterer in NY  State:  Are you being charged sales tax on the service/gratuity charge.
 I  have finallyfound the perfect venue, which, of course, costs much more  than I had planned.  They are charging a 20% "service" charge and NY  State sales tax on the total price of per plate plus service.  I  contacted NY State department of taxation and finance.  Tax law says tax  does not apply if 1. the charge is separately stated on the bill.  2.  if is specifically designated as a gratuity and 3. all the monies are  paid over in total to the employees.  The caterer is stating the charge  separately and swears all the money is going to the employees; but they  are adamant about calling it a "service" charge rather than a "gratuity"  and charging me sales tax.  So if anyone has a caterer who is not doing  this, please send me the specifics as I would like to challenge this.  
Thanks,
