It seems that some drivers are back at work - there was a delivery to my local Mercadona supermarket of bread, dairy products and some fruit/veg, but the smaller shops don't seem to have any problems. There's not much met or fish around at the moment, but this may change before the weekend. You won't go hungry, but my find that resturants and beach bars have a very limited menu. The bars are still getting beer deliveries
As far as petrol/diesel is concerned, there are several garages which have sold out, but the service area on the A7 toll road near Benalmadena had petrol yesterday and there wasn't much of a queue. The panic buying seems to hve stopped, both with petrol and food.
I'll post again tomorrow if there's any more news.
