So, I went to this restaurant after a high-class job interview with my friend and the waitress was very cute, but not pretentious about it. We chatted a bit when she came by, IOIs and the like, and I decided I'd ask her out. I pussed out and didn't ask her directly but instead wrote on the bill my number, email and invited her to a concert. I didn't expect to hear back. Five days later she emails me this "Hey it's Lucie from the Highrise grill. I like your bold move but unfortunately I'm going to deadmau5 Oct. 1st. You should come back sometime though and mayyybe we could have a drink after work..."
I feel like she'd be in control if I emailed her back saying "sure, I'd like that" or something like that. Should I just show up a couple of times close to closing with a few friends and hope to go from there? Try to set up something else by saying "I have a better idea, let's .....(adventure date)." So, advice?
