What's a frugal thing you still do despite being HENRY?

Anything people still continue to do to save money which, tbh, you shouldn't need to if you are taking home £100k+pa

Examples

Yellow sticker items at supermarket. I've had to learn to restrain myself and leave for those who actually need the saving

Only putting on washing o/n to get cheaper tariff

Sitting and waiting in a car to not have to pay for metered parking just before cut off time for free town parking
