bad treatment, i could have slapped the staff that works at the door

Good day,

I bought a Mongoose bicycle pump(TYPE A) but then there was something missing, I went back to game yesterday to change it, 1stly when I got to the shop the security guard and lady seated to the right gave me such rude treatment because I had on a face shield which I’ve been wearing for a year now, they said I must put a mask under the face shield, I told them that I was on lunch and would just like to exchange and quickly. But the lady pushed me out of the shop telling me she’s gonna phone the security of the mall, Like im a beggar or *****, less of a human I then went to get a mask very frustrated and then went back, I had to rush in order not to be late for work, when I got home then I noticed that they gave me a cheaper make of the pump (type B) please find the attached photo. I don’t know whose gonna pay for petrol, time. If I was too return to that shop, I would probably loose my patience. Location: Lenasia Trade route shopping mall
