Loyal customers should be treated with respect

I bought a shoe for my son,obviously it was to small and I returned it for something else. I then chose a beautiful shoe and the cashier advised me that it won't last to long. So I went back to the aisle for a different pair of shoes. I struggled because nowhere could I find his size in any kind of other shoes. About literally two minutes later as I'm still going through the shoes A very irritated sales lady approached me in a very irritated tone Halfway demanding that i hurry up because I'm holding up the que.

I feel that I'm the customer and have the right to choose a shoe for my child that would make me and him happy. After all I'm paying... having one cashier on front line is not my problem..they need to sort themselves out.

I ended up taking big size because I just grabbed and wanted to get out of the store.

Very disappointed and highly unprofessional to rush a loyal customer of PEP
