It can be anything!!
I will start..
I am a food safety inspector (local authority) and have been for over 15 years, working in two large cities, and my current job in a smaller local authority. The same theme...
Food handlers do NOT wash their hands properly after using the toilet / before preparing your food.. lack of antibacterial soap in a toilet cubicle or in a kitchen is common place.... even when I am there, hands are not washed, it is an absolute bug bear of mine.
Preparing with raw meat then handling food ready to eat.. not uncommon
Handling cash / touching screens then handling food.. not uncommon.
Yes it does put me off eating outside of my house unfortunately 🙃
I have come across a LOT worse but this example irritates me.
Your turn!!!!!
