Used a Groupon
No different then any other location I've been to.
When I showed my Groupon to the guy working behind the counter. He didn't say much, except for the fact I owed .35 cents.
This was the first time when using a Groupon that I was charged GST.
Also my wife had given him a frequent users card to get stamped, and he refused to stamp it.
Groupon users lose at this location.
I paid for this Groupon, and should be considered as good as CASH !
