Great laboratory, but the queue ... I arrived at 9:30 and there were at least 30 people waiting on the street on a rainy day to enter. The worst thing is that he leaves us no choice but to wait ... I've been here for 30 minutes now and without anticipation of entry. Wouldn't a little more organization help? Or have to make an appointment? This would limit the capacity and would not leave anyone on the street.
