Some customers think they can save money by tricking professionals and choosing to go DIY.

This man had a client who requested a late appointment and then tried to take advantage of his expertise.

So, he decided to handle the situation in a smart way so that she couldn’t trick him.

Check out the full story below for all the details.

Measure twice.

I measure and fit window blinds for a living.

So many of my days are spent traveling around the city and trying to find parking.

Then measuring and quoting for blinds that I will be fitting if the customer wants to go ahead.

I work for myself, but days can be very long.

This man was asked by his customer what the measurements were.

I had an inquiry from a lady who insisted that I come early evening, much later than I would usually work.

Anyway, as I was up my ladder, she asked if I could tell her the measurements.

I said “no.”

And explained that this is my skill set and how I make a living.

So, he added and subtracted a few inches from the original measurements.

So I wrote down the sizes for each blind.

And I added 2 inches extra to the width and subtracted 2 inches from the real height.

Just as I guessed, I caught her snapping a photo of my pad with her phone.

I never heard from her again.
