Using coupons on the first date

I don't want to sound like a snob, but... what would you think if you were talking to someone (a normal, working, single man) on a dating app for a couple of weeks and you finally set a date to go out. Everything seems great in the planning process until he suggests "Let's go to ____, I have a coupon."

Is this a red flag? Are you a snob for not wanting to go out anymore? Doesn't it feel like something that could just be... saved for not a first date? Five star restaurants aren't necessary, but choosing a place based on a coupon?
