Sales

It may be the case that a change in disposable income or some other reason why people have less money to spend may not only affect visitor or customer numbers but may also affect sales. 

For large organisations such as theme parks an important source of income is ‘secondary spend’.  This is the amount of money spent by visitors while they are in the theme park.  This would include spending on refreshments and souvenirs. If people were feeling a bit hard up they could still afford the visit to the theme park, but reduce their spending by having less refreshments or not buying any souvenirs.
