When you do excersice
Unless you pay extra
If you get there early
Unless he is going to pay you
When you buy online
you have to buy your snack
you get the basic service
drink plenty of water
don't do it
Unless I phone to say I'll be late
When you fly on one of the budget airlines
wait for me in the hall
If you don't receive tomorrow
you save ten per cent
give me a call
expect me at eight p'clock
