I find the 'available 24/7' comments on some AW profiles very dubious.
If a garage or corner shop is open '24/7' it means I can call at 5am and at least expect someone to be there. When they say that on an AW profile they ususlly mean, "I can be bothered doing an early morning call if you arrange it a few days in advance." Which is perhaps reasonable - given that no-one stays awake, much less has their hanging fanny out for work, 24/7. But it's not accurate.
