Customers should not be bound by "terms and conditions" that are written in very small print (say, less than what is typical in a newspaper) or which run on for pages. There should be a minimum print size and the extent of small print should be limited to, say, 500 wards.
Why does this idea matter?
Many people will ignore these conditions anyway because they are difficult to read, very, very boring and often lengthy. However, they might find that they are bound by something that haven't had the time or the stamina to read. If small print is necessary, it should be made more readable. If it isn't necessary, it shouldn't be there in the first place.
