Splash-Out

I wanted to buy two tops and try them on before purchase. I asked the sales woman very politely if I may try them on?, she asked me if I was wearing makeup I said yes I do. Then she handle me a white plastic bag and said I must pull it over my head and face!!!!!I asked her is she was joking cos I don't see how I could try on these tops with a plastic bag covering my head and face????? She said if the tops gets dirty she can't sell them! I said I been shopping in all my life I never heard something so stupid policy! Of course I did not buy the tops!
