Quite sometime ago, we bought discount vouchers from Groupego without reading the fine lines. Turns out we could only claim it in the time frame between lunch and dinner, weekdays.
Whoops! It took us a lot of trouble to claim the vouchers and have the meal, and we vowed to read the voucher carefully before buying. At least the nasi lemak served in Hailam Kopitiam is pretty decent, though we can't vouch for the other stuffs in the menu.
