Getting used to strikes

I've never really been affected by strikes so far, either because they just didn't happen or because even if they would, in Switzerland even though there's a strike people outside that industry aren't really affected by it.
After the cleaning personnel of the metro in Madrid was on strike in December, now it's the truck drivers that are protesting against the high fuel prices (such as in other european countries). The problem is that not all the drivers are supporting the strike so there have been some nasty scenes when "piquetes" - representatives of the striking drivers - have tried to "inform" the others what the strike is all about. As I've been told their ways of convincing everybody to participate are usually quite violent, involving for example to stab the tires of the trucks to prevent them from delivering their goods.
And here we come to how we get affected by the strike, the other day a whole shelf of meat was empty, there were no packed fruits or vegetables available and some of the other shelves also start showing empty spots. Combined with some farmers in Almeria as well protesting it looks like there might not be any fresh tomatoes next week, but as we discussed, the empty spots might also be caused because people go out panic-buying whatever there is. So for the moment we're not starving and since some kind of agreement was signed it looks like there's not gonna be any big problems for us to get some food.
