Plus or give 15 minutes

The contributor of this one said it, talking about the time. It was “eight thirty, plus or give 15 minutes.” This is an excellent example of a congruent conflation (blend of two idioms with the same or similar meaning), combining “plus or minus” and “give or take”, both suggesting an exact number may be below or above the estimated amount. A big thanks to curioussteph for sending this one in.
