For those of you following this story...
I was shortchanged after my lunch last Monday at the Manchu Wok downtown. I posted my experience here, and I also wrote a note to their corporate office, and so did several of you ! (Thank you!)
I received, in the mail to day, a hand written note from the owner of the franchise, which reads:
I am sorry for giving you a bad experience on Monday. I should have trusted you as a customer and handed you your change back. Please accept this $10.00 included.
So, I got back my change, plus what I spent on my lunch, and an apology, after having to contact the corporate office. I still won't go back there again....
