We have those even at supermarkets in the UK. "Would you like to round up your £1.10 shop and donate 90p to our nominated charity?" and similar gets really irritating after a while. I think the solution is to legislate that any tips solicited this way for third parties need to have the company match your tip. For the US situation, it's totally down to the stupid way that minimum wage is defined, where tips are counted towards the minimum wage. In the UK, there's a reasonably generous minimum wage (£12.21 per hour for age 21+) from the employer, and tips would be on top of that minus appropriate taxes.
