Any 10-1-10 brides nervous about this? Others welcome to answer.....

So, there seems to be a pattern with some of my vendors confusing our date to be 10-10-10. This happened at a limo appointment and now I found out with my DJ too. The DJ one could've been worse but luckily my sister works for them. The owner told her how he has turned down a lot of parties for my date and that it's so popular, 10-10-10. She's like nooooo its the 1st. He says really I have the 10th written down, check with her and get back to me, as if my sister doesn't know my correct wedding date. Nooo on my contract it clearly has 10-1-10 and he had booked another party for that night but changed it around so that he is still dj-ing our wedding. This is totally freaking me out a little bc when we arrived at a limo appointment the guy did the same thing oh popular date not sure if I'm still available then we explained it's the 1st not the 10th. I hope our vendors are carefully checking my date when they book others. I'm going to confirm all of them again and make sure they have the 1st down and explain why I'm double checking.

Anyone else have to deal with this at all?
