I had two people (including David) from Party Services So Cal help out at my wedding this past Sunday. We had bartenders, and a served buffet lunch, but I forgot there is a lot more to hosting a party for 75 people than just having the food out there.
I made a last minute decision to get some more help, so the hubs and I wouldn't be running around for ice or restocking the desserts/non-alcoholic drinks. I confirmed the booking on Friday, and didn't remember to call to check in until Sunday (the morning of the event).
They just rolled with everything. They were on time, were willing to do all the random stuff we asked, and were always around helping clear stuff out, and doing whatever needed to be done. They cleaned up, and gathered our mass of stuff we brought from home. My friends even dragged them into the photobooth at some point for some group shots because they enjoyed having them around so much.
I cannot recommend them enough. I didn't have to worry about anything with them around to make it looked like I had planned it like this all along.
