Alf is appalled by the gall of some people (poofters and lesbians, in this case).
They are able to take advantage of a free service, but complain they have been short-changed.
These contemptible ingrates – when they go to McDonald’s restaurants for a burger and fries or some of that good-health tucker now available – can tap into the internet if they want. For free.
It’s a nice little extra service that the food chain provides.
But are the poofters pleased?
Nah. The buggers are dismayed to find they can’t tap into so-called “gay” websites.
So they are publicly denouncing the restaurant for the shortcomings in a service that is provided for free.
