well Les i don't believe in giving tips, i don't see why people should be expected to, you've paid for a service, where do you stop? do i tip the bus driver?, someone on the checkout ?, little joes school teacher ? pay people a decent wage so they dont to rely on tips
some people cant accept tips or gifts, my misses while working in A&E had seen patients who were worried about their health they went to A&E, and after she assured them that they were fine, they were that relieved they had gone straight out and bought chocolates, flowers etc, but my misses had to refuse them as its trust policy.
