Looking at it from South East England, this shows what a huge business commuting is. Probably millions of people commute into London every day. Train fares (which are expensive), taxi fares, coffee shops, takeaway food, pubs, restaurants. Since lockdown people who have been working from home have found that they suddenly have plenty of cash on hand for a reason. Commuting is big business and that's why some are lobbying for commuting to resume ASAP.
