Are 3 day BOB's obsolete?

[Midnitemo]

Strangely enough thats exactly what i did on tuesday, took my car for service in Worcester(less than half the price of my local dealer£129 against £341)got my bob out the boot and off i went along the canal Just over 3 miles each way, got some funny looks off the service guy, even funnier when i came back humping a propane bottle i'd found lol...anybody know who services the old shellgas acct as i want to swap it in for a full one and shellgas have sold out to somebody?
