There are some cases where a tip is absolutely not required. If the vendor is the business owner, there is no need for extra cash unless you insist. Additionally, the tip may already be included on a vendor bill as part of a "service charge." Nor does a tip need to be in monetary form. For instance, you can give your wedding planner a spa ticket or bottle of wine instead as a thank you. Sometimes a personalized thank you may suffice. It is best to prepare all the tips and divide them into individual envelopes in advance. To stop running around on your own, appoint someone on the day of taking care of all the tipping. You can also arrange the day before, to deliver the tips.
