"Mute" spectator

Today, I left the office at around 6pm and took the way out of campus via the rear exit of Manyatha Tech Park as this avoids me hitting bad evening traffic on Outer ring road. It was a beautiful dusk. A bit sunny as sun was still visible at the horizon shining over the yet-to-be-completed tall concrete buildings around.

I dropped at nearby shell service station for refueling my Enfield Bullet. After top up of fuel tank, I reached out to get a filling of the tires with Nitrogen gas. There was a guy, station worker at that Shell petroleum outlet, who was busy doing his work of setting the PSI units to prescribed values and filling up the front and rear tires as fast as he can. He waved at us and called upon all two wheelers in the queue as he was working parallel on all front tires of all bikes at once and then setting the pressure to a higher value for the rear tires to work smarter. (A nice efficient scheduling algorithm indeed!) But there was a man with his scooter who was in need to break this algorithm and wanted to be FCFS! (First-come-first-served). He was very upset of the way he was waved and asked to wait for filling up of every other bike's front tires to get his rear tire done. He went to manager with a complaint that this worker is showing hands at him and asking others to move ahead of him and break priority. Manager rushed to the place as the guy was still continuing doing his work of filling air. Manager revealed that the guy is deaf and dumb and does show only hand signals to communicate. I said to the man in scooter that he was doing his work in parallel so that it saves a lot of time. But the man left grumbling over the petty issue making a big fuss. The manager who stood next to me said that even though god has given him everything, he shouts over this poor guy who is deaf-mute. At least this guy isn't begging or stealing but doing a service at station for earning some money. The man was already long gone with his two-wheeler to even lend an ear to those words. I stood a "mute" spectator after listening to what manager said as my thoughts lingered around the same but the guy was busy filling up gas for the next car in queue without knowing what all had happened until now.
