1. It’s a waste of time going to look at new cars if we can't afford to buy one.
2. It’s no use buying Joe a football game if he doesn't like football.
3. I can’t help falling asleep in front of the TV. I’m so tired at the end of the day.
4. There’s no point in complaining to the manager about the food now that we've eaten it, we just won't come back here again.
5. I can’t stand going to busy bars and restaurants where there are crowds of people.
