Business partnership advice needed for Food Business

Need honest advice.

My friend offered me to join a bhature chole franchise business. First he said we’ll do 50-50 partnership. Later he changed it and said his uncle is also involved, so now it’ll be 30%-30%-30%.

Their side is doing the investment which is around 5 Lakhs. My role would be managing the whole shop daily:

\\- staff management

\\- customers

\\- stock

\\- operations

\\- opening/closing

\\- overall management

My concern is not just percentage. It’s trust and clarity.

I feel weird because the structure changed later. I don’t know if things were hidden initially or if planning is just unclear.

Also, if profits don’t come for months, then what? I’ll be working full-time with no guaranteed salary and only profit share.

What would you do in this situation?

\\- Is 30% fair if I’m managing everything but not investing money?

\\- Should I demand fixed salary + profit share?

\\- Are these early changes in partnership structure a red flag or am I overthinking?

Would appreciate practical advice from people who’ve actually done food/business partnerships.
