Male customer shouting at women

An middle aged male customer walks in the pharmacy asking for his prescriptions which are kept on the file at the pharmacy. I asked him to repeat his full name - I think he got frustrated that I couldn't find it immediately and he starts shouting:

Man: I gave it yesterday! Look properly! 

Me: Hold on who did you give it to, I'm still looking.

Man: I don't know! It's there, it's there! 

Me: Ok found it. 

Man: See! You didn't look properly.

Still shouting ... 

Me: Ok relax. I found it.

Man: Hurry up, I'm in a hurry! 

Still shouting.

Me: Say it again, and I'm gonna do it even more slower (under my breath)

Man: Hurry up!!

Still shouting.

At this stage, I'm already pissed off so I'm dispensing the script pretty slowly. Like very slowly. Typing one letter with my index finger one at a time and then deleting it, logging out of the system and do it again. Checked my Facebook for a bit too. 

He stands there waiting with an angry look on his face. I ignore him.

When I felt the time was right, I dispense the script, scanned the meds and proceeded to charge him at the till. 

Him: You know its morning and sometimes you gotta be nice to sick people.

Me: Doesn't mean you can go and shout at people like that. 

Him: What DID YOU JUST SAY?

Me: I don't like people who SHOUT at me. 

Him: You are very rude. (throws a $20 dollar note at me) . As a lady, you should act like a lady and be gentle and nice. You are not very nice. 

Me: No you are very rude. You are not a gentleman. You don't shout at women like this. Be a man. (pointing at him with my index finger).

I put the change on the table and walk off. Had enough already. 

Him: Don't put money like this. You need to put the money in my hand! 

Me: Don't throw money at me then. 

He was fuming. 

Dude, this is not your home and I am not your nationality and I don't abide by your cultural thinking/etiquette of women beneath men. You don't come into my pharmacy and start being rude expecting me being nice to you. I stand up to anyone who is rude and you are no exception. There's a fine line and you've stepped over it. Don't care if you're a customer or not. Being sick doesn't mean it's acceptable to vent and treat strangers in a way you don't want to be treated. Especially when you made that comment about how women are suppose to be, shows you are an egotistic dominating demanding male. I don't care how you treat your women at home. You're not gonna get that treatment out in the real world mate.
