In my dads case he dide not have a good time he had to have a operation on his arm the first one he had did not work the second time he went for another operation on the same arm the surgeon told him that from looking at his scars and reading his medical notes there was no way that they had done what they say they did ( the surgeon who operated on him the first was no longer there).
this time round they preped him ready for his op then they left him there for 2 hours when they came back they told him he could not have his op done today,
then they told him to go home and come back in 6 months he had already waited 18 months for this one, lets just say he was not very happy.
