Meaning of "catch-as-catch-can policy"

Dear teacher,

Please explain “a catch-as-catch-can policy.”

Thanks.

Hi mlngvt,

You asked for an explanation as follows:

This means that you try to catch someone in whatever way you can manage. If it is used as a policy adopted by a company possibly selling insurance, you are asking your sales people to use whatever method they like to attract future customers/clients.

Apparently the expression comes from an old style of wrestling where the two contestants fought each other without any rules about what they could and couldn’t do in the way of holds.
