I worked at KFC near school for almost 3 years, quit halfway through year 12 because of school workload even though i was only on 1 shift a week. I guess it depends on the management team but its not a bad place to work. The pay is okay once you finish your training and the people were generally friendly. I worked in the kitchen rather than front of house and it was a very demanding role with a lot of product to cook and a kitchen to keep organised and clean all by myself, the other option was working on the counter/drivethrough and packing the meals people ordered, so if you're okay with people that was generally the easier option since there were plenty of people but usually only 1 cook.
The point is its an
okay first job. I wouldn't say it makes you hate the food but your uniform
will forever smell like kfc so dont wear good pants with the shirt they give you if you do end up working there

EDIT: forgot to say that once you work there a while you can kinda work the shifts you want, they give new people the later shifts but after a while you can ask for better ones. The close shifts go really late and involve a lot of cleaning and are generally seen as the worst shifts. I guess my evaluation was based on being there for three years, so it's important to mention that it
was pretty bad at first but got better and became okay after a year or so.Have you considered tutoring nliu? Or working for a lecture company like connect or tssm or something?
