The DIY chain has reportedly also told workers that they should be prepared for "sensitive" customer questions regarding rope, cable ties and tape.
The allegedly leaked memo, named "Preparation For Fifty Shades Of Grey Customer Queries", outlines that staff should be "polite, helpful and respectful" to those potentially looking for bondage gear.
It's thought all 20,887 staff at the brand's 359 stores received a copy of the memo, which warns, "staff should prepare to handle potentially sensitive customer questions".
Each store will also receive a copy of the book so that employees can familarise themselves with the erotic tale.
Ahead of the film, which hits cinemas this Saturday (14 February) and stars Jamie Dornan and Dakota Johnson, the guide also mentions a preview scene where Christine Grey heads to a hardware store to purchase such equipment and points out:
"Rather than bought for home improvement purposes, these products are intended to fulfill Mr Grey's unconventional sexual pursuits."
But if you think this is all a bit over the top, think again. The memo also explains that when the book was released in 2012: "DIY and hardware stores in the UK and US reported increased demand products and queries from customers as they tried to recreate their 'Fifty Shades' experiences."
A spokesperson for B&Q was quoted in The Telegraph explaining: "B&Q remains committed to serving our customers in all their DIY needs. Customer satisfaction is always our number one priority."
