Well as reader....your cards is your tool.
You shall threat them with respect...you shall keep them in a nice cloth....you shall give them your energy.
A reading are then an interaction between the cards and the reader.
For me it will then sound strange to give the cards to the questioner to shuffle.....because the connection between reader and card then become broken.
On the other hand....when the card is shuffled...the questioner might choose to cut the deck in one, two or three ways...and that I find alright.
This was my view on it
