My gosh, this is by far the worst voucher I've redeemed from 51. It's good I only bought one. Upon arrival last night, we were wondering why ZenQ and ChaMeCha at the same mall were overflow with people while StarTea was completely empty, even though there're large writings outside that offers buy 1 get 1 free! I now understand and would never ever step foot into that place either. The voucher states it's 82% off of $5.50, with savings of $4.50. The cashier argued that it's only for $3.50, not $5.50 as stated in the voucher. After some arguing, she offered to give me for $4, but then ended up still charging me $1.70 (50 cents extra for my $4 drink plus tax). Noticing that I was reading the screen to see why I had to pay so much, she quickly turned the screen off! Then the drink came. It tasted like the whole cup was simply filled with milk, it's supposed to be milk tea!! Minutes after drinking it, I started to feel sick. I ended up vomiting a few times last night, with my entire dinner flushed down the toilet. I know the vomiting is not from the dinner as we went to our usual restaurant which never gave me a problem. The health inspection agency should really go check out this place and prevent others from getting seriously ill too!!!
