Absolutely pathetic airline

You know I get that there’s strict restrictions in the industry when it comes to passenger air travel, but I honestly feel that what was experienced with @FlySafair this morning was just completely ridiculous. My dad, a loyal flysafair passenger who has only ever flown with them for as far as I can remember, was just denied boarding because he was THREE MINUTES late and was forced to buy a new ticket. Now keep in mind, this happened at the check-in point- meaning that after entering those boarding gates, he still had a good 40 minutes before his actual flight departed. I understand the reason for certain restrictions, but take into account that my dad was standing close to the end of a short line of passengers that were boarding the same flight waiting to be checked in. And those 3 minutes forgone was probably because of the nonchalant attitudes that the attendants had, and out of the almost 10 terminals, there were only about 4/5 people attending to the queue. So thanks to the airlines unprofessionalism and inadequate staffing, we (YOUR CLIENT), had to fit the bill. I mean I get that you’re a business and getting that currency is your main concern but don’t swindle your customer out of their money based on “technicality”. Be upfront and charge increased prices on your airfare if your main priority is to increase your profit margins. Transparency over deception is much more appreciated. And speaking of technicality, on the new ticket notification that he got it states that boarding time is 8:55am and departure is at 9:25am. Correct me if I’m wrong, but the time between 8:55 and 9:25 is about 30mins?..... (please refer to my previous views on deception) So thanks to you guys my dad had to wait an extra 3 hours to board another flight. Which doesn’t fare well with someone who already finds the whole experience of air travel to be an angst and stressful one.
