A couple weeks ago, a local business was hired to come to my workplace to perform a service over a three hour time period. We paid in advance--the invoice was broken up into:
Service to be performed by two employees
Travel/setup fee (they are practically next door, so the fee seemed pretty high...)
Tip (we decided to tip 20%, rather than a higher amount, because of the travel fee.)
Well, it turns out one of the employees was not able to make it, due to personal reasons. The owner of the business refunded the service fee for one of the employees, the travel fee, and half the tip. She also is sending another employee over this week for the same three hour timespan, free of charge.
The other organizers and I have decided to hold a drawing, so a limited number of people will have a longer amount of time with the employee (rather than the majority of people getting a very brief amount of time with him/her.)
Would it be tacky (since it's a workplace thing) to suggest to the drawing winners they ought to leave a tip? My inclination is that I should, but this is so not my forte, professionally speaking. I presume the employee will be paid for their time, but I have no idea who the travel fee goes to or if they're paid a small base hourly wage, like waitresses, or if they get paid a flat rate regardless, or what. Thanks!
