I used to carry tools but in 12 years I never used any of them, I'm never more than about 6 miles from either work or home where there are tools, so in a rare case where I might need them, I'll just walk, walking is good too.
At various points on my commute there is a Meijer, Walmart, Home Depot, Trek dealer, and non-chain LBS. The bike stores don't open until 10 am, but the Meijer and Walmart are 24-hour and HD opens at 6 AM. Before I had my kit sorted, I used each of them. The only unrecoverable incident was when a crank arm's shoulders rounded and fell off. The dealer had to order one and I picked it up two days later.
