Morning Star Travels — rude behaviour of the driver/attendant

Hi,
I had booked a seat in morning star volvo bus from rajahmundry to bangalore, boarding at morampudi junction on 18/05/2018 vide ser. No.129 (Ka-53-aa-999) for my son.
While keeping a fragile item which contains mango pickle near the seat, the driver/attendant said rudely not to keep near the seat but in luggage space. He went to the extent of abusing my 80 years old uncle and a lady "don't you have sense". Is this the way to treat and behave with passengers, that too with ladies and elder persons?
Again, during dinner break, my son asked him "where can i have my packed dinner" he said very rudely "go and have outside, not in the bus".
There should be some politeness while dealing with passengers, who are their source of income.
