To be fair, at least in Spain, things get really slow during the summer, basically from May to the end of August, even if "officially" everything is just "slow and closed" during August. During August, anything productive is basically impossible to get done, the months around are still slower than the rest of the year.

Of course, "European companies normally ignore their paid customers too from May to August" is factious, but there is a slight hint of truth in there, in that things generally is slower, at least in the South/West countries I'm more familiar with.
