Punctuation, is it too much to ask for?

I don't think that the person doing the sewing is named Jean. I don't know for sure, but that is probably a reasonable assumption.

Rather than identifying the person operating the sewing machine, I think that this sign is identifying the service on offer. Rainbow Dry Cleaning will hem my jeans.

I know this may seem needlessly petty and pedantic, but accurate punctuation can also be financially significant. A comma in a telecommunications contract cost the buyer millions.
