Would you tip a pest control team?

[MrsCakeBaker]

My mum has a pest control company round to proof her house against mice. There are a couple of guys there who´ve worked for five hours, cleaning and disinfecting behind cupboards, the fridge and the oven, all of which they had to move and then and put back, and blocking any access holes.
I know it´s their job but, in view of the fact that they´ve been so thorough, my mum wants to tip them on top of their already hefty (I think) charge.
Would you give them a tip?

No. And any professional outfit wouldn't accept a tip anyway.

A cold drink would probably be appreciated

No but would supply plenty of drinks

Nope. Cold drink or a cuppa.

No I wouldn't and they probably wouldn't accept anyway.

I would, especially in this weather make sure drinks were available for them.

My mum would want to though too OP.

Excellent! Thanks for the replies, everyone -- very helpful. The cold drinks have been flowing, also tea and cake. 😊

Lovely 😍
