Hello this review is fro Glass Mosaic Canada, I bought a groupon for a two hour class, when I arrived I was told that the groupon was not valid, I asked why and the owner said we stopped doing them, I said well I made a appt and had him look up my name in his book which was there, he then said I had to pay a material fee of $79.00 I said my understanding was the fee was between 12-15 dollars depending on the piece you made, He then said "what do you think I am made of money, I dont even make money on the Groupon, this is Canada I'm not doing this for nothing. All this was being said in front of a large group of people, and was very imbaressing to me. I siad i was not going to pay $79 for a $25.00 course and he said fine then go. How do people who are so rude, disresptful and down right mean stay in business... It boggles the mind I would never go there again, in a big city like Toronto to go and learn about Mosaic's
