The reason why some people are cynical about eating food outside is that one can never really be sure about what they are being served. From stale to purely adulterated the quality of the food is always questionable.
Just to validate it for you, in a test run by BBC's Watchdog programme, faecal bacteria has been found in ice at McDonald's, KFC and Burger King across the UK.
More than 10 random branches of these popular food chains were examined and bacteria, known as faecal coliforms was found. 3 McDonald's samples, 6 of Burger Kind samples and 7 of KFC samples were found contaminated.
The ice at all these stores was tested for coliforms and has been advised 'not-safe' for human consumption.
It's extremely worrying. When we're finding the sorts of numbers we're finding here, you have to look at the people making the ice, handling the ice, which they then transfer into customers' drinks.
And then you also have to look at hygiene failure with potentially the machines themselves,are they being kept clean?
It is pleasing that Escherichia coli (E. coli), the bacterium that is the most accurate and reliable indicator of faecal contamination, was not found in any ice samples from McDonald's restaurants.
Low levels of two other indicator bacteria, coliforms and enterococci, were found in some ice samples.
These can be used as an assessment of water hygiene but, as they are widely distributed in the natural environment, they are not reliable indicators of potential health risks.
