This is more of an etiquette question.
My aunt's boyfriend has been good friends with this guy who happens to be a dj in my area. My aunt suggested him cuz she's heard him and thinks he does a great job. I trusted them, got in touch with him, and told him how I heard about him. He told me he'd do my whole wedding (approx 6 hours) for $350 because he trusts his friend and wanted to do me a favor. So I'm really happy about that, I book it. Then we listened to him at this local bar (dj/karaoke) this weekend. I really think he's a great guy, his wife oversees everything to make sure it runs smoothly, and he played some great music.
I asked my aunt and her boyfriend if I'm suppose to tip him on top of the deal he's already giving us. He has his own equipment, doesn't hire anyone outside to do work, he basically just gives us his time and has a lot of the music we want already. Her boyfriend said to tip him like $50-$75! I'm thinking what's the point of the discount then? My fiance's parents said they didn't tip anybody at their wedding, and they think it's crazy to be expecting extra when the whole point was to get a discount.
Any advice would be appreciated! Thanks.
