Postbank staff dismisses senior citizen needing oxygen!

Today we took my 76 year old mum that is oxygen dependent and in a wheelchair to Shoprite Checkers in Randburg Square. We went straight from her hospital appointment she takes her tubes with to use the oxygen at the hospital. we arrived and asked the security guard if she can be attended to, they said no everyone must follow the queues. She had to choice but to wait as she is house bound and rarely leaves the house due to requiring oxygen. We dont have a portable tank we explained numerous times to the security and the ladies from Postbank who didnt even blink at the dire situation. We waited in line for 4 hours, as we get to the front of the line, another customer comes in with oxygen and they let him walk to the front of the line!!! Naturally we were livid, and asked for answers. The security was rude and dismissive that my mum is not on oxygen even though we showed them her tubes she carries around. Is this how you treat senior citizens and people that are frail and require a bit of empathy. This was shocking they allowed the young people in as first priority over the older people all sitting quietly waiting to be attended to while the security guard and the Postbank staff laughed and made fun of these situations. We have photos of this situation and will be sharing on social media as the dismissive and arrogant behaviour of people who should be serving the country is beyond revolting.
