Poor little rat! But then it will be appreciated for years to come.
Coffee, meal, presents? Wow! Here you get a cup of tea / weak coffee and a biscuit. The choice is either to wait for 'the daughters of dracula' to visit unannounced, which means if they get it wrong there's no one to seek advice from (and it does), or to go a long way to somewhere obscure to do it (60 miles / 2 hrs round trip), when you're not to drive for a while afterwards so you'd need a second person to get you back, and for which you'd have to take time off work anyway which isn't going to happen.
I've never given blood: by the time I weighed enough they didn't like my teeth.
And they wonder why only 4% of the population do it.
It's sort of funny that almost everybody instantly goes "poor little rat"!
I see it differently... I believe that the life goal of every single cuddly animal is to be very, very important to a single human being. So important that it has to come along to all kinds of different places and is sorely missed if that does not happen. Missed, and searched for.
Added bonus is being totally unique, and other human beings going "ooooh".
So, according to my estimation, the little rat should be a very, very happy cuddly animal now, with all these boxes checked. (It, or rather he, has acquired name in the meantime, too, and been important and appreciated in two sessions already. And taken places...)
Your blood donation circumstances really don't sound so welcoming! They are always looking for new (or more) donors here as well, though I don't know which percentage of Germans does it. If things go wrong here, there's several doctors who will rush in and do things - I've seen people hooked up to IVs in the very dire cases, so they do take good care of their volunteers.
