you can count  roughly , how much burger they need to sell

don't forget other misc expenses , labour cost , food cost .

the Major part is due to HIGH rental already ' occupy " a lot .

FYI that Thailand one they already claim WILL NOT COME BACK SG.
Partly Must be due to High rental also , just that mainstream media news don't wish to report. Only report they will not coming back SG next year.

You dun worry for them. If they cannot make money they won't rent. The fact that they rent year after year shows that it is very profitable.
