It has been annoying for a while but our last departure from Barajas T4 was the worst, Sunday, last Nov 26 2017. The two officers on booth 12 left and right for Non EU travelers were terrible. The lines were the longest I have seen, the entire area crowded to the max.
It is not uncommon to see the officers engaged in conversations while they are checking you or not calling people in because they are too busy talking. That Sunday Nov. 26, these two officers were talking non stop from the moment we got on line ( we could see from the distance) and continued until it was our turn, over an hour after. Our two lines on that booth would not move and when it did make it to them officers it was obvious that they were not paying attention the job either, perfunctory.
We, all passengers fearing we were going to miss our flights were wondering about a supervisor around but it there was no one around and also we feared repercussion if we complained.
It begs the question about security also. How could they be paying attention to security issues with travelers while they are so engaged talking?
Somebody must pay attention to this matter at Barajas Airport.
