Deedaa your post highlights the main point that I felt offended by.
I think that this person really wanted to move to London and would be trying to secure a similar job to what he had in Afghanistan, ie a very well paid CEO. I think he didnt want to go to Scotland as London would be a better chance of obtaining this sort of job, not for the company of fellow refugees. And I feel that he saw delivering pizzas as beneath him. That's what I found offensive. I feel that all jobs are essential none are more worthy than others. We would be in a right mess without cleaners, bin collectors, shop staff etc.
Lack of public toilets in towns.
