Yes, the door should be opened for the girl before she gets into the car- she can get out by herself though
Casual or in a suit really depends on who you’re dating and what number date…
And eating out on a first date is not so uncommon but for the girl its rather uncomfortable– my friends and I are fine with a lounge for the first date, it’s what we’re used to.
arcades and board games: don’t do it for a first date-but you can discuss it with the girl on the date and decide what to do from there.
**for all those people that say lounges are awkward and uncomfortable: face it, a first date IS just that. you’re meeting someone you don’t know from a whole in a wall and “evaluating” them as a potential match.
