Singaporeans were super excited to hear that In-N-Out Burger would be organising a pop-up on March 6, 2019 at a cafe in Upper Thomson:

Even though the event only lasted for three hours with limited servings available, that did not stop Singaporeans from queuing like their lives depended on it.

A video of the queue was uploaded to Facebook:

In case you can't see, here are some screenshots:

According to The Straits Times, the first customer started queuing as early as 6:30am, even though the event only started at 11am.

Wristbands were given out at 7:30am, and 320 of it were snapped up within half an hour, ST reported.

Each wristband allowed each customer one burger, which ranged from S$3 to S$5.

Here are Singaporeans' photos of the burgers:

My first ever @innout burger! BURGERS ARE CURRENTLY SOLD OUT, ALL 300 of them! (when it was supposed to start at 11am). And queue is about 2 hours! Staff are advising people to stop queueing - as they might be queueing for nothing. News aside, pretty legit good burger ($4 for cheeseburger, $5 for double-double).
