Greggs in Tewkesbury

I visit this place fairly regularly. Don’t go around lunchtime as they won’t have anything and don’t go in the morning as food is cold. Food should be kept (whilst hot at a minimum temperature of 63°C for a maximum of 120 minutes. So tell me why when I arrive at Greggs at 6:30am (30 minutes after they open) my sausage bean and cheese melt is bordering on cold and my sausage roll is luke warm. This is neither enjoyable or acceptable. They should learn food health and safety.
