What is customary to tip the servers & bartenders at your wedding? I have seen that if your DJ, photog, etc. owns his/her own business, they should not receive gratuity. In our venue contract, it indicates that the service charges is NOT gratuity for the servers, etc. - but they are compensated by being paid a higher hourly wage.
What are you planning to tip, or did you tip? Do you give one lump sum to one person for all the servers?
