Don't tip over

Tipping your wedding service providers is generally expected, but not required. How much and who you tip is at your discretion. Tips are given to reward extraordinary service.

Pay close attention to your contracts because some of them might already include gratuity.

Calculate your tips before your wedding day and place the cash in separate labeled envelopes for each vendor. Designate someone (who you can trust) to distribute the tips.

It's also a good idea to put some extra cash in a separate envelope to have just in case a bill is larger than expected or someone goes above and beyond.

Here are some guidelines of who to tip, when and how much:

Bartenders: A bartender should be tipped 15 to 20 percent of the total bar bill. Make sure their gratuity isn't included in the catering contract. And, make sure your guests don't tip them by displaying a "no tipping" sign.

Baker: Usually not tipped. You pay a flat fee for their services.

Caterers and reception site managers: Typically a 15 to 20 percent tip is included in their contracts. If the caterer and/or site manager is extremely helpful you can give them an additional tip of $1 to $2 per guest.

Chauffeur: The driver usually earns 15 to 20 percent of the total bill if it isn't included in their contract. Don't tip until after you arrive to your destination safely and on time.

Delivery personnel: $10 per person is a nice gesture for anyone making a delivery on your wedding day. This can include your florist, bakery and rentals.

Entertainment: Tipping is optional for your musicians and entertainers. Tips usually equal $20 to $30 per entertainer. DJs are tipped 15 to 20 percent of their fee.

Florists: Usually not tipped. You pay a flat fee for their services.

Officiant: A civil officiant is not allowed to accept tips. He or she earns a fee for performing the service.

Parking attendants: Usually $1 to $2 per vehicle is given to the supervisor prior to the wedding. Don't permit the attendants to accept tips from your guests.

Photographer: Usually not tipped. You pay a flat fee for their services.

Restroom and coat check attendants: These attendants typically receive $1 per guest. The money is typically given to their supervisor before the wedding.

Waiters and servers: The wait staff typically earns 15 to 20 percent of the food bill. Caterers sometimes include this in their contract.
