Go for blood and nearly get locked away

Well, I've just got back from the hospital and it was touch and go whether they were going to let me out again. I went in for a blood test and a cheeky CT scan of my sinuses (as part of the ongoing investigation into why I keep getting a temperature and getting ill). Had those, but my stomach has not fully recovered since leaving hospital last time. It's generally grumbly and not being very polite and after I eat it has the audacity to hurt. Most un-british like of it. So, I thought, as I was there and as I felt a bit under the weather anyway, I'd pop in and see the doc and see if they had any amazing ideas. They didn't but as my temperature was 37.7 they were umming and arring about incarcerating me again.
"I've served my time, damn it! ", I protested.
"Guards! Take him down", was almost the reply. Instead, they checked some more results and as nothing was untoward, they let me go with a caution.

Oh yeah, the blood test. It only took two goes this time, but it was the lord high supervisor doing it, who is normally top of the pops and gets blood quick and with prowess. I guess my leather veins are a force to be reckoned with. Hopefully, I will leave a legend behind me, which trainee blood letters can be scared with by their supervisors.
