When I was at Grin Affair one late afternoon, when I witnessed a family group coming in at around 5.55pm but when they wanted to place their order using their Groupon voucher, the staff told them that the voucher can only be redeemed before 6pm and the time is already 6.02pm.
The elderly lady who had the voucher looked aghast and the group left in disappointment. Maybe there's some detais in the interaction that I didn't witness but if the cafe where to refuse the groupon redemption due to the timing techicality, then I think they are missing the point. Mmmm, I thought groupon deals are meant to draw new customers to the cafe in the hope that some of them will like it enough to return and increase the customer base in the process? Furthermore, the cafe is only 20% full at that time.
The jar cake and waffle I tried were OK, durian ice-cream was great but the pricing is a bit steep for its location. Also, I am not likely to return to a place that treats customers in this manner.
