Toby Carvery complaint: Warm food and no stamp given again

Was very disappointed yet again warm food spoke to the floor manager and said disgusting. She did however say she would warm me out but I’m not having my food note in a microwave. This is not acceptable. They should be doing temperature checks on that food every so often to make sure that it adequate for people to eat.. it was our friends birthday there was eight of us at the cost of £13 per adult meal plus drinks so it wasn’t exactly a cheap meal and we could’ve gone other places but I do enjoy Toby Carvery but this isn’t the first time I’ve complained about the hotness of the food. Also I asked the lady to stamp my card which now I’m supposed to be getting a free meal, cause I’m on my third stamp again it says 24 hours to come through. We went at 5 o’clock Saturday and I’ve still got no stamp on my wallet I don’t normally complain but when you go out for a meal and the cost of it nowadays plus drink it is unacceptable to keep getting Luke warm dinners temperature checks like I said need to be done to make sure that food is piping hot especially the veg and the potatoes, look forward to hearing from you Mrs Richardson
