Respect

My grandson, Ryan, recently quit his job as a bagger at Engles because the customers did not give him respect. He cited the story of one customer who, after Ryan had bagged all his groceries, put them into a very full cart and hesitated about putting one more bag of a single jar of pickles and searching for a spot to do it, the man suddenly grabbed the bag from his hand and stated, "give me that, you don't know what the hell you are doing" and walked out. The lack of respect was too much for Ryan, even though he needed the job. Where does this "respect" idea come from? We hear of blacks that shoot one another because someone disrespected them. Why is that? My upbringing on respect was to respect your elders which was accomplished by standing in order for the elderly to sit. To say, "Yes sir or Yes ma'am" to inquiries from elders. To shake hands when meeting someone. Take a hat off when in the presence of a woman. To seek a chair for an older person and make them comfortable. I have observed Ryan come into the house and leave his cap on. He sought the large easy chair to sit in and left his grandmother standing. While eating, he does not look around to see if his table-mates need anything, he instead concentrates on his own food. What is wrong with this picture?
