<human>: I'm going to rant a bit here, sorry about that. The person I'm venting about is from the USA, let me stress I don't think it's typical or comical, she just happens to be a US citizen. This not a US bashing thread, I've had other problems, as bad, with other countries.

So I work for an EU based insurance company offering policies covering worldwide travel and medical assistance. We had a file in which a client of us (16yo) needed Surgery urgently asap. So we ask our colleagues in the US to send a GOP to the hospital on 09/25(noon around here, early morning there), they fail to react so I call them during my nigt shift on 09/26 (still 09/25 in Atlanta but late in the evening) and they say they'll do the necessary, however they don't.

Today we sent them another mail requesting they place a GOP. 4 hours later we get a mail from them explaining the father had in the mean time already paid ($ 7000.-) today. Than two hours after that I get a call from this lady at the american office who is a bit pissed of because she received a mail requesting to place a GOP. I explain it was sent 6 hours ago so 4 hours before we were informed about the father having paid already. She says yeah well there's a huge time difference between EU and USA. I try to explain that yes there is a time difference, but 6 hours ago is still 6 hours ago so it was 2PM in the states when we sent this mail and 6PM when she sent hers. 

This is not possible according to her as she says she spoke to me around 03PM (Atlanta local Time). Again she asks we quit sending mails because she already explaines the father paid the hospital bill in her mail. 

Again I try explaining our last mail was sent before she told us this. Her answer is again: time difference. I explain I wasn't at work this afternoon at 3PM Atlanta local time but was sleeping. To which she again replies: 'I told you there was  huge time difference!' and slams the phone. 

I'm baffled how someone like that isn't locked up in a mental institution but working in an office for an insurance company providing medical assistance.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Person workin in an office seems to think an hour in the US has a different lenghth than in Europe and a mail sent between the two will travel for several hours to comply with time differences.
