Bad client experience

So I had an employee from Makro stopping me and telling me that I should buy spanks at Woolworths in Galleria and that they are R240. It is not appropriate for any of your staff to comment on what I should wear or what I should not. Do they know why I have a big stomach? She even said that she stopped me because Im in her age group. Do you train your staff to guess people's ages or age groups? When I am at Makro, it's because Im there to buy something and leave. If I had a problem with my weight or even my stomach, I would something about it. What gives your employees the right to insinuate that I should use spanks to flatten my tummy? I didnt het her name as I was rushing to the tills as the store was already closed but she is fair in complexion and had a braid wig on.
