You can " Offer to pay for the date" and see how he acts? If you dont fancy the guy then insist on paying for your share, do not lead the man on and make him thinks by paying for the date he has a chance meeting you again.
From my personal experance with men in the UK is that around 80% of the men will pay for the dinners&drinks, 20% will buy you a drink and just wait for you to buy them the next round.( those are on my block list )
Once establisd the relationship, both party should pay , he makes more he pays more, you make more you pay more.
