What a palaver

MacBook charger broke after someone put chair leg on wire.
Brother in Law doesn't have spare.
Ordered one to collect in store (£65)
Picked it up and immediately realised it was wrong one.
Swapped it but told him it was 15 inch screen not 13 - I'm amazed that matters.
Got it home. Thankfully didn't open it and did more research. Kept receipt.
Went to Trafford Centre - asked an Apple specialist. He said it would work. Set off home.
Then thought - "Did he realise it's for 15 inch screen version? Did I tell him?"
Called back at PC World. I immediatly found correct one. The same person swapped it again...
Got it home, opened box...and it wouldn't fit. Things went critical and meltdown ALMOST ensued...
Then I took off the clear plastic cover ...and it fitted. Major incident averted.
