You really don't have a single clue if the business is failing or not.
My wife used to work as a franchiser for 7/11 long time ago and now has a lot of friends who opened those fried chicken kiosks and coffee shops are pulling a decent side income of around 20-30k a month per kiosk as a side business. They all have a job and a provident fund and this is just a side hustle to them. The investment to open a such franchise starts at 10 thousand baht and most do it because they literally get free training with it. Don't know how to make a coffee, waffle, bubble tea of fried chicken? You simply open a franchise and get free training with hands on experience.
Also, many of these kiosks are registered on every single app... Grab, Food Panda, Robin Hood, Shopee and 10 other apps you don't know about.
So, I bet you 80% of them do not fail. They just move on to better things or simply do not have the time to manage.
