Chuck:

Thank you for cleaning the urinals. I hate using a stinking urinal.
Thanks for keeping the toilet seats clean. I hate bad surprises.
Thanks for cleaning the sinks. I hate trying to wash in a scummy sink.

At home I keep my toilets and sinks clean. And I don't get paid for it. Congratulations on getting paid for it.

People who put someone down for doing a disagreeable job are likely the ones complaining the loudest if the job isn't done. In fact, they just enjoy complaining.

And especially, congratulations on your retirement. I hope it is long and enjoyable.

Kerry
