Which one of these events happened yesterday evening as I was trying to get my yardwork done?

a) I was 90% thru mowing and mower ran out of gas.
b) I was 50% thru weed eating and eater ran out of string.
c) Wal-mart employee told me, "We no longer carry replacement weed eater string. You have to buy the replacement spool for $8."
d) All of the above.


P.S. Wal-mart is the devil
