It's a first date. Don't waste money on needless experiences as the real testament will be if you and the person you're dating can connect on an emotional and personal level. As cliché as it sounds, being yourself will be your ultimate goal. Don't be fooled by trying to imitate techniques or personalities to get to a second date. There's a reason so many people can't maintain relationships and that's because they're trying too hard to be something they're not or lack general maturity.
Best of luck, don't overthink it. Work on being you and the best version of you.
