The first 30 minutes for me would be:
Making a brew, having a look what was required, going indorrs and reading the haynes book of confusion, making another brew, having anothe look, deciding it's too cold, finding warmer clothes, have another brew, head back out, realise it's too dark, find a lamp, have another brew, have another look, go to the toilet (too many brews), come back, have another look....... decide it's too complicated and put everything away.
Even that usually takes more than 30 minutes :lol:
