On the 20th of September I was travelling with my wife and our daughter and after being on the road for over 6 hours driving from Portugal we arrived in Santander where we waited about 1 hour until reaching the check-in counter. Myself and my Daughter are Portuguese citizens and my wife is from Macau holding a Macao SAR passport although we all reside in Portugal where she holds a EU resident card, the staff without checking immediately assume my wife was Chinese and demanded a visa without consulting the passport in hand. I explained to the staff that my wife is holding a Macau SAR passport which grants 6 months visa free travel to the UK, however the staff simply refused and didn’t bother to check. I showed the staff the official web site from the https://www.gov.uk/check-uk-visa where it shows the 6 month visa free travel, I also showed previous entries on the passport to the UK but this was disregarded. I asked to talk to someone in charge but the staff said the person cannot come nor could he/she talk over the phone. Being stuck I had no option but to drive from Santander to Southampton by taking the Euro-tunnel. This took us two days and more expenses for travel than original budgeted. The staff in Santander are clueless and heartless people and the person in charge should be fired immediately for this issue.
