Whilst agreeing with you your point 1 isn't strictly true. The stadium facilities are available for hire (my wife's been to a function there) and the shop is open, as is Dick's. I appreciate that the income from these isn't anything like a match day - but then even on match days most of the income (from STH sales which make up the bulk of the crowd) has already been banked whether the 'customer' turns up or not. I do believe expanding the non-match day stadium income is one of TB's priorities.
Fair comment, but as you say the numbers involved are not great, but better than nothing.
