I'm trying to total up all of the many smaller expenses in my budget and am a little stumped on tips (who to tip and how much). Can you all give me your thoughts on these vendors: hair (on location- I am paying a travel fee); make-up (on location- I am paying a travel fee); DJ (owns his own company...is this merit based at the end of the night?); Second Line Band; limos (gratuity is included in the price...give a little extra anyways?); and carriage. Am I missing any? We haven't decided on a caterer yet, so I am not sure what the gratuity arrangement will be for that. Bartenders? TIA.
