Early morning meeting? No problem. Lie-in until 10, have a shower, a light breakfast, slightly too many cups of coffee then dial in 7am and arrive before anyone else. Look smug.
Can't be bothered to wait 10 minutes for dinner to be done in the microwave? Easy pop back in time, put dinner on, return in time for the ping.
Neighbour's dog keeping you up at night? Easy pop the Squiddrel* over the fence and enjoy the silence (after about 10 minutes). Actually that has nothing to do with time travel, but it is fun.
Annoyed by the slow service at your local fried chicken takeaway? Go back 50 years, replace the Colonel's 11 different herbs and spices by a mixture of sulphur, charcoal and saltpeter. When you return to the present the orders will be literally flying out.
But my favourite thing of all is sharing a nice cup of tea with figures from the past. Marilyn, JFK, Thomas Edison, Brunnel, Granny Smith. Last week I went for a brew with Nikola Tesla. The conversation couldn't have been more interesting, but I was unable to make my hair lay flat for a month afterwards.
