I try so hard to avoid Walmart because of these reasons! When people have the audacity to look at me and treat me like I'm inconveniencing them because they are having a conversation and I'm trying to shop, I push my way through them while excusing myself, and if given any attitude, I look at them and say "WHAT?" (when said in an exasperated, fed-up way they usually shut up). I wish people would just be more considerate and take their conversations outside to the parking lot so the rest of us can get our shopping done!
As for the rude employees..they're a joke and I just laugh at them! Everyone has to work for their dollar...like it or not, they're no different! Kudos to your daughter for ensuring that at least one person in Walmart that day earned their dollar!
