Ever feel rushed when reviewing your hotel bill? Here’s a quick way to check hotel or cruise bills for accurate restaurant and other purchases where a gratuity is included:  During your stay, adjust the amount of the tips so that each room charge ends with the same digit. For example: Add enough of a tip to end each charge in an odd cent (17.03, 25.43 …. Notice the ‘3’ at the end of each charge).  It takes only a moment to scan the bill for items that do not end in ‘3’ and thus may not be your charges.  The odds of an mischarged bill ending in this odd number (‘3’ in this example) is low.
