I'm a DJ who performs at wedding receptions. Here are 10 things guests should never do at a wedding.

Don't complain that the music isn't to your taste.

Don't try to book me for another gig.

Pricing up a DJ set at a wedding isn't as simple as, say, pricing up a club night.

Some people want to hire a DJ for the whole day, while some just want one for a couple of hours. Some venues require only a small setup, and others require the whole shebang. Some choose to have their weddings locally, while some choose to have them in the middle of nowhere.

All of those things affect how much it'll cost you to hire me for the night. Let's talk about it, sure, but not right now. Take my phone number instead.

Don't ask to plug your phone in and play your own music.

And don't ask to do a speech.

Please don't ask to do karaoke.

Don't tell me how you're related to the bride or groom.

In relation to the first point, if you want a song playing, telling me you're the bride's sister or the groom's brother (or any variation of the sort) isn't going to help.

Again, it's their night. Their choices come first. Plus, it's my job to make sure that the majority of the guests are also enjoying the night. 

Drum and bass at 7 p.m.? "Oh, you're the best man? Why didn't you tell me?!"

Don't pretend to use the equipment.

Don't bring your drinks near the kit.

Don't interrupt the first dance.

Tell me I'm the best DJ in the world.

You don't mean it, so don't say it. Do you really think my ego needs stroking that much?

Yes, yes it does. Continue.
