What was the last thing you splashed out on?
Have you ever been broke?
Why are tourists sometimes ripped off?
is it always a bad thing to pass the buck? Would you keep a friend if they were a cheapskate?
If you had to tighten your belt, what could you give up?

1. если у тебя в начале is, то должен быть глагол в инговой форме
