A resident living on the second floor is experiencing excessive smoke from the first floor due to an open grill between their flats. They are seeking to close the grill but are facing opposition from their brother who lives on the first floor. While legal remedies are mentioned, the advice strongly suggests seeking an amicable settlement through discussion, potentially involving friends or relatives, as legal action would be costly and may not be applicable. Installing an exhaust fan is also proposed as a practical solution to mitigate the smoke issue.
