Our place already offers free water bottle refills but we also offer bottled water (still/fizzy) for 30p a go - the number of people that are amazed at the low cost is staggering!
I kinda thought the avid cyclist would carry a basic toolset - that side of it doesn't bother me as we have many, many day-cyclists around here that do the run on hire bikes for the scenery and exercise. I've even carried one exhausted lady and her bike into Oban (a 50 mile round trip for me) as a favour and on numerous occasions taken the unprepared back to their local hotels (they ride out thinking it's 'easy' and 'not that far' only to find they can't get up some of the hills and it's a "damn sight further than I thought"

)
A secure bike stand will be part of the attraction when stopping here but given the opportunity for theft (about 'zero' - I mean, where would they go that we couldn't just follow them?!) it's less of an issue.
Nice comment on inner tubes and links though

..... that's the kind of stuff I need. I also wasn't aware that HEX keys are the tool-of-trade on bikes

I'm still of the 'one-spanner-with-lots-of-holes-in-it' guy......
Any more???
Don't take it personally......
