No balls

There's this visitor who totally pissed the shit outta me.
One fine night, my coworkers and I were sorta relaxing as there aint visitors and this 30 ish chinese visitor/cg came up to me and complained.
About kids playing around with wheelchair when there aint even enough wheelchair.
And he said 'Hope you will tell them to stop fooling around. If you don't do so, I'll tell them personally or call the police.'
Immediately, I wanted to reply 'Go ahead and call the police. Don't bother us with all this.'
I despise this sorta man (is he even a man at all, no balls at all!) who needs someone to pass the message cos' they simply don't have the balls to tell others off themselves.
Why would he need us, a TEMP CLERK who is only in charge of registration to convey the message?
Why would he need a POLICEMAN, who is prolly busy with some other SIGNIFICANT (murder, rape, robbery etc) cases?
This totally proved that he has NO BALLS.
Do you think the sheriff would even bother to entertain him?
I would like to them him straight at his face :
'Sir, the police wouldn't entertain you because
1) The wheelchair is not YOUR property, it belongs to the hospital.
2) The lady is really hurt, she is limping, she might need the wheelchair as much as your mom.
3) You make a police report not because you feel that you would be doing justice to other patients but because of you ownr personal nasty experience, your own personal feelings. It is selfish of you to do so and you need to sort them out.
4) You are a man, why don't you have the balls to them straight in their face?
5) What made you so sure that at that point of time when your mom fell , the wheelchairs were used by teeny boppers who were playing around with it?
6) Wheelchairs and complaints have got nothing to do with us, the screening counter staffs. We basically help people to register only. You want information? Go to the info counter. You wanna make a complaint? Go to Service Quality department? WHEELCHAIRS? Wheerchair bay / info counter staffs. Can you tell how IRRELEVANT it is of you to ask us, who has got nothing to do with the above to settle your personal grudge against teenagers who you alleged played around with wheelchair thus causing your mom to fall without the use of it? It's like asking the pharmacist about surgeries, cashier about the ingredients in the curry puff etc (you get a gist of what I mean?!?)
7) I CAN'T EMPHASIZE MORE ON 'BE A MAN'
8) No use crying over spilled milk. Don't push the burden / responsibility or attribute your mom's misfortune to anyone. Why have you never thought for a single second that you were the one who didn't support your mom well thus she fell? Why don't you carry the blame, be responsible for it?
