The UK middle classes have long shown disdain for British people who go to mass tourism resorts like Benidorm and Magaluf, waxing lyrical about their own more "authentic" travel experience. But these travel experiences are still relatively brief, selective and involve at best fleeting glimpses of meaningful cultural exchange.
Indeed in many cases the experience that the middle class Northern hemisphere traveller has comes at great expense to the comfort, security and well being of the citizens whose country they visit - beaches protected by armed guards, luxury hotel staff living hundreds of miles away from their families with no running water and so on. Unlike the tourist in Spain who will generally be catered to by people on EU mandated wage scales and living with much the same amenities and protections as the people who visit their country.
So given that we all go on holiday to have a break from real life and experience existence in a temporary state of stasis, is it really so much worse for someone to choose to spend this time in a mock English pub if that's what they want to do?
