WeatherHeavy rain, cold weather and snowstorms affect the number of people who come out to dine.
Equipment MalfunctionsEven if you have good equipment and keep it well maintained, problems occur. Air conditioning systems, which have to cool large areas continuously, are notorious for breaking down in very hot weather. Compressors malfunction and coolant leaks. People will not dine in uncomfortable conditions. Theyre coming to be entertained and served, and theyre paying with their hard earned money.
Unforeseen CircumstancesTerrorist events and major breaking news stories affect customer numbers. When the O.J. Simpson verdict was announced, our restaurant was empty, even though it was a beautiful, sunny day in Philadelphia.
Every time the daily break even sales number is missed, it means that the next days break even number must be even higher, and if the number isnt made during an expected big business period like a Friday or Saturday night, it makes it that much harder to meet your monthly break even.
Remember, there's a set number of weekend nights in a month, and if theres a bad snowstorm or another unforeseen circumstance during one of those weekends, sales will be behind for the whole month, and its almost impossible to generate them any other way.
