Yeah, I think I'd find that awkward too! But still, it is worth mentioning, even if you inwardly acknowledge that you may need to pay for it yourself.
We were going to buy a new arial for our place recently and mentioned it to the agent (we intended to pay for it ourselves - just wanted to upgrade) but she said she'd talk to the owners and they did agree to pay... And it got done really quickly too! So it is always worth asking, I reckon
GL!!!
