we get a free hot drink and snack between 3pm and 5pm each day it comes as part of our menu pack.
If this is what you are referring to?
no this is different.
The offer Leopold is referring to was for cash payments and applied to everyone. For example the last time I was in DLP in December 2013, I had lunch at Blockbuster Cafe in the Studios. At the end of the till receipt was a voucher for a hot drink, which could be redeemed between a certain time in various locations.
The idea behind those type of vouchers is to increase footfall during quiet times of the day and to increase customer spend, the idea being that you go in and redeem the free hot drink, which has a low profit margin and then buy a cake or sandwich which has a high profit margin.
Disney probably stopped those vouchers as people were only getting the free drink and not buying anything extra.
