It’s not a good idea to pick your date up on a first date unless you already know them. If you have met online and this is your first date, then you probably won’t know where they live, or they might live quite a long way from you, in which case it would be too far to pick them up anyway. You might want to be courteous and offer to give them a lift, but it might actually put them off, as you are still relatively a stranger to them. If the date isn’t a success then you have the uncomfortable job of driving them home afterwards. If you’ve never met, then it’s best to arrange to meet at a particular location and each make your own way there.
