You want to know which hawker stalls are going to be kaput very soon, these are the main indicators:
1) A stupid 'act cute' logo and/or signboard.
2) A prominent wall of text writeup about the background story of their food, displayed at the stall.
3) Hawkers are attention whores who liberally give interviews to 'food bloggers', 'influencers' and the trashy 'journalists' from SPH/CNA.
Essentially, they are merely narcississts who think too highly of themselves and whatever food they are selling.
Remember this and you will easily identify which stalls will suffer the same fate.
