Reports of the demise of cash premature?

[MacAdder]

Fast food places that use Just Eat get stung so much with their charges that many will try to encourage the use of cash in store as much as possible.
Not using Just Eat puts them at a disadvantage as many of their competitors do, so they're stuck between the devil and deep blue sea.

Now there is something I really don't understand, why people use Just Eat.

Go direct to a place that delivers for half the price!
