Subway recently opened a small branch inside the Martins newsagent in our local West Swindon Centre (which admittedly has progressively become more of a dive over the years). The result is the newsagent stinks of their product which also permeates out into most of the plaza at that end of the place. Not sure how they even got permission for that arrangement as there seems to be no ventilation to extract the smell and fumes to the outside. It is so strong it actually makes you feel nauseous. As the local Post Office is in the same branch I've now taken to driving to another location for stamps, sending parcels etc.
