Thanks Backpacker & Pamelar, if that's the case I think we'd all agree that legally you're squeaky clean. The other point I was alluding to was that as soon as you are flying on a 'mission' of some sort rather than purely recreational flying, your decision making process will come under the influence of external factors which invariably work against flight safety. The go / no go decision cutoff will inevitably be skewed when commercial pressures are added to the mix. It takes some discipline to remain objective and make sound decisions and there have been plenty of PPLs who have ended up in smoking craters as a result of 'pressonitis' or pushing it a little too far. It's easy to scrub a fun Sunday afternoon flight if the weather looks a little dodgy - not so easy to cancel when the boss needs you to meet an important client to clinch a big contract. Your personal limits will shift slightly because you want to do your best for the boss and your job - maybe only slightly - but they will shift. Be careful.
