Airport checkin delay

Recently,  it took about 30 minutes for me to do security checkin, though,  I carried single hand bag. The reason is insufficient trays to keep our belongings for scan.

So everyone was tense with the thought of missing their flights, except those who are early. I too keep atleast an hour between checkin and boarding time and thus had some spare time.

The issue is the weakest part in checkin process is insufficient number of trays.

Like in material handling with chains, we say the weakest chain link decides safe lifting.
