Wedding dress attempt

I went to David's Bridal with my sister today. The lady wasn't very nice. Granted I arrived at 830pm, and the store closes at 9pm...I didn't have a reservation. Still, I'm a fast shopper. I had to fill out a form. I already filled out that stuff online, but she didn't even ask about that. She's a bad sales lady. She asked when my wedding day was, and I told her. She said, "You better order a dress soon." I was thinking, "what's that supposed to mean??" So I asked how long it takes to alter a dress. She said about 12-16 weeks. I said that's fine. She gave me a look like..."You better get one soon or else it's not going to be done in time." Lady! I've been engaged for month, I have other things to take care of besides my dress. I only want to try them on anyways. Not like I was making a purchase tonight. Geez...sorry...venting.
