Family Dollar complaint: Double bagging

I walk everywhere due to a medical condition. I shop several times in a week. I buy a lot of heavy products.(Ie cat food) I spend about $1000.00 a month just on this. I run a business here locally so it convenient if I need something. Well normally I buy reusable bags. I had forgotten them and did not want to buy anymore so I ask clerk to double bag the items since I was walking. She refused stating they do not double bag. How ridiculous is that. I have had bags rip open before in the middle of an intersection. I was extremely mad . I’ve boycotted dollar general over something. This is ridiculous. For the cost of $.02 you prefer to lose a well paying customer? I am a disabled veteran as well as 58 yrs old ,I walk for medical reasons. I run a business and am part owner as well as my family owning businesses. I’ve never heard of this policy. Is your company that desperate to save a penny?
