J S Laundromat & Dry Cleaners

Cleaned my vintage blue coat. It looked right purty & sparkly.
Two weeks later. Bought a gray raw silk blouse. Wore it to work the next day. Dropped tomato on blouse. STAIN.
Took it in to the cleaners. Dude said he’d do what he could. Came back two days later, looked through the plastic: stain gone! Yay!
Walk two blocks home. Lay blouse on bed. Remove plastic. Find dark gray square-​shaped spot by the collar. Walk two blocks back. Ask him to explain what that is.
Of course, somehow, that has to be my fault. I somehow didn’t see it when I brought it in. Or I somehow did it in the 15 minutes since I had left with my «cleaned» blouse. I suggest that’s not the case. He suggests that what I am saying «is not true». I bristle at being called a liar. Suddenly notice a coil of square stickers on the counter– hold the stain next to one, and see that it’s the same size. He looks at it, looks at me, snatches it away, and says he’ll «try to get it out». Gives me a receipt and a sullen glare.
Happily, the stain did in fact come out… or else I’d have been out $ 100. I suppose he left the sticker on during the cleaning and the chemicals cause the adhesive to stain it. But, come on; that’s just careless. And also dude? Don’t call your customer a liar.
