The heater continues to grumble

My spouse & I always like to get dressed up and go out to our preferred eating establishment for our anniversary and other big events together from time to time.  All of us have been going there now for several years & look forward to the great food, the wonderful atmosphere of the venue & the comfortable feeling all of us get from simply being in the eating establishment.  Well this past anniversary it all did not quite task out as planned. All of us made our reservation as always & arrived right at the stressed time however as soon as all of us entered into the eating establishment all of us knew something was feeling very wrong; The eating establishment had a number of box fans running in the bar section, as well as in the dining section & it was unquestionably sizzling that day inside the whole space.  All of us asked the hostess about the overwhelming heat & she apologized saying that their air conditioning equipment had recently failed however the Heating & Air Conditioning service people were already on their way & it was sure to be repaired momentary when they arrived. All of us decided to stick it out & hope for the best. I soon heard many people grumbling about the heat at a nearby table. All of us easily decided to order a frozen drink to help cool us down and chill.  Not long after all of us arrived, I noticed a Heating & Air Conditioning service van quickly pull up out front of the eating establishment. Two service men ran into the building & were shown to the back of the eating establishment; just as all of us were being served our ice cold salads, cool air could be felt flowing from the overhead air vents & the whole eating place started to cool down.
