I have an Italian Ice business and have been doing events for four years. Some require a register tape as they take a percentage of sales. Some require you take tokens that they sell, and then they pay you out at the end of the event, less their percentage. Most allow you to handle the sales and simply charge a space fee.
When handling our own sales, we start with a "bank" which is counted and noted in a form. ( Bank can be a metal box or an apron, depending on the type of event and volume.) Then at the end of the day, we count the "till" and subtract the starting bank. We record our sales on a form I have created that also has other info: i.e. Event name, dates and times, notes on the weather, how many food vendors, how many frozen dessert vendors, what we were selling (sometimes we add other things into the mix). Use this form to look back at previous events to determine value and sales. (After doing a lot of these, these notes become very valuable!)
We do have a register, and, at times, have separated out items to see what items sell relative to each other.
Counting cups can be a problem in that sometimes cups fall and have to be trashed, or people ask for an extra cup, or.... this is not a reliable method.
