I am curious to hear from servers who may know the answer. I notice the following scenario. Server brings check in a folder. I pay with credit card. Server rings up charge and brings me slip to sign and place gratuity. I do and place card in my wallet and the charge slip back in the folder.
The server arrives a few minute later and opens the folder in front of me. I am curious as to why?
1 - is the server making sure I signed?
2 - is the server making sure I took my card?
3 - the server is taking a peak at the tip?
4 - Combo?
Can they think of being more discreet?
