relating classes to work

So today at work we had a customer came into our house and he had a total mental down in the middle of the office. I would like to say he has a mental disease but i'm not very sure which one. He was upset about his bill for this month and when the customer service stuff tryed to example to the man about the minimum bill he throw himself on the floor and started screaming like he was a 3 year old child. I was blow away by this whole thing and since we are reading about mental disease's in psychology I would have to say he either has a mental disease or is under a lot of stress which is cause this break down. We weren't able to get him to relax or even to sit up in a chair. Which he went into this fit he wasn't hearing anything anyone in the office had to say. We ended up call the police dept and asked they come with the fire dept because of what was happening with this man. Once the cops came he still didnt really relax but they did talk to him and call his wife which we came to find out the man has a mental disorder and that he may be off his medican. So felt to bad for this guy because i've never come across this before other then my Aunt which is bipolor, but when it comes to her she has more of a mood swing then a mental break down like this man had today at our office. I do believe after watching this whole thing this morning that some people really do have a mental sickness that does need medican and doctors care. I feel so bad for people who have different disorders which effect there everyday life.
