One of the rudest experiences I had in Montreal!!!! I ordered a tart,walked 4 meters and went back to ask them if I can get a cheesecake instead. The owner refused in a super rude way. I offered many scenarios like paying the difference in cash but she was simply was lazy and rude. At first she lied and told me she can't do reimbursement for transactiobs less than 5$. when I told her the transaction worth 8$, she told me she can't technically do that. When I offered to pay the rest in cash she told me she can't because "she already put the tart it in a plate and can't return it to the fridge"!!!!
