Firstly, hamburgers. Hamburgers to me is like a hot bod male with gorgeous locks reading a physics textbook whilst composing a acoustic solo, playing Call of Duty like a pro and giving cunnilingus all at the same time. I LIVE FOR HAMBURGERS.
Secondly, in Singapore vegetarian choices are often never financially justified. Compare a Vege Delight sub to a bowl of minced meat noodles or pay $6 for a small Caesar salad (without real bacon)
Thirdly, choices are hard to find. It's been very difficult for me to even try going vegetarian without Subway around (as my sure go to). There are only a few coffeeshops around my work place which have vegetarian stalls and they don't look quite as appetising at all.
