Cold callers, self-service checkouts and hand-wash only clothes are among life's biggest wastes of time, according to a new survey.
Caffeine-free tea and coffee, automated telephone systems, soap operas and TV ads also feature in the top 50 list.
Social media also looms large as a 'time vampire' - including aimless tweeting, pointless videos and instant messaging at work instead of speaking to colleagues.
Scrolling through Facebook five minutes after the last check, and waiting for YouTube videos to buffer also feature in the list.
The average Brit claims to waste an hour and 42 minutes of their precious time every day, and wishes they could spend it doing more useful things - getting jobs done around the house and pursuing hobbies and interests.
That's the equivalent of almost 12 hours a week wasted on things such as playing mind-numbing games likes Candy Crush, recovering from hangovers and purchasing coffee on the go.
The study* shows the average person spends hours waiting - for people to call back, parcels to arrive, delayed trains, pages to loads on the computer, queuing, food to defrost and the washing machine cycle to finish.
For those respondents with families, much time is spent arguing over homework, booking doctors' appointments and cleaning the house only to watch everyone trash it again five minutes later.
Packing a shopping trolley, unpacking it onto a conveyor belt, packing into shopping bags and then unpacking again is also something which annoys many.
Untangling ear phones, removing a ridiculous amount of packaging from a small item and browsing properties online which you have no intention of buying also feature on the list.
In fact, the average person reckons they waste at least one whole day a week at work, and could save an hour a day in the workplace if they didn't have to deal with unnecessary meetings and phone calls.
While most people admit to wasting an hour and 24 minutes using social media and surfing the internet every day.
