Dora and Vicki are bartenders. Dora prefers her tips in cash because she can have the money right away. Credit-card tips dont get paid to the bar staff until the payments are processed, which can take a few days. Vicki still prefers for her customers to put her tip on their credit cards. Why is this likely Vicki's preference?

• Customers are likely to spend more on tips when using their credit cards rather than cash.

• Cash tips are often dirty and may even smell of alcohol.

• Credit card tips are a more accepted form of payment in the stores where Vicky shops.

• Vicky is more likely to save her earnings if it takes a few days before she receives her pay.
