Delay at Calais Car Ferry Port

When travelling by ferry from Calais to Dover on Friday 13 July, we were delayed by 1 hour, 40 minutes by UK passport control at Calais. Apparently, of the 10 available windows, only 4 were manned, of which 2 for trucks and 2 for private cars. Six lanes of traffic including trucks and coaches had to narrow and cross-over to reach the respective windows causing such a delay. The French staff said they had asked the UK passport control to open more windows but either staff were not available or they did not wish to do so. Whatever the cause, we did not appreciate such a delay.
