Cross contamination

This is the fourth time in the last couple of weeks I seem to get the same lady telling me I cant dunk my chicken fillets.This instruction is from management, reason being" its cross contamination".Dunked chicken wings is not problem but dunked chicken fillets is an huge issue, then I suggested I will take it separate in a tub, then they have an lame excuses we don't know how to measure it. I have no idea why some staff at KFC will have no issue, and the *********** people will always have an excuse. I mean i pay extra for the sauce so WHAT IS THE ISSUE???? So I hope Management can sort this out ASAP.

THank you
