Researchers who polled 2,000 adults found that the top 50 list also includes Wi-Fi not connecting, supermarket self-service tills and feeling "overworked'.
The research also revealed that British people complain three times a day on average.
One in six said they are most likely to complain in the morning, with traffic during their commute cited as their main worry.
And one third said they complain less at the weekend.

Geoffrey Dennis of the Society for the Protection of Animals Abroad, which commissioned the research, said: “Most people in the UK acknowledge that they complain about trivial matters on a regular basis.
“When we’re used to modern conveniences like Wi-Fi, home deliveries and air conditioning, it can be easy to forget that others have to deal with far greater problems every day.
“For people in Britain, everyday problems can seem like the end of the world – and most of us are guilty of complaining about things like bad weather, traffic or people pushing to the front of queues.''
The study also found that many British people prefer to complain in private, with 45 per cent waiting until they’re home before they voice their concerns.
One in five of the survey's respondents said that there is a stereotype of "moaning British people".
But one fifth said they tend to block out others who moan about their "first world problems".
Around four in 10 respondents said they complain more now than they did as children, and half said they feel better after "getting things off their chest".
More than half agreed that there are far more "moaners" today than there used to be.
But some respondents said that complaining works, with four in ten having received money off their restaurant bill after making a complaint.

One in four people agreed that if they complain enough about the price of things, then something will eventually be done about it.
However, almost half of the survey's respondents said they could go a whole day without complaining.
Mr Dennis added: “These kinds of inconveniences are so minor compared to the problems faced by many people and animals in the world’s poorest communities.
“Working animals in developing countries never complain, but they have every right to.
"These horses, donkeys and camels endure incredibly hard lives, carrying backbreaking loads in punishing conditions, without the food, water, rest and vital vet care they need.”
“In developing countries, many working animals have to walk huge distances, pulling heavy loads across difficult terrain, working in temperatures exceeding 40 degrees Celsius.

“These animals often have no veterinary treatment available to them when they are sick or injured.
''That’s why SPANA’s work is so important – preventing suffering and ensuring these hardworking animals receive the care they so urgently need.”
