You get 10-minute breaks, but you can't stay out and eat or go to the toilets for that long, because it takes a while to scan your fingerprint before they let you in again. If you've got sweaty palms, then this is really a thing to consider!

For me, it took only about a minute or so for that, but I was still in a bit early; didn't want to take any chances!

thanks DanaJ..

I was under the impression that the breaks are each 5 minutes ones..
