Inna, if you are going to provide an appliance it must be in usable condition for the guest.
Yeah, every guest teaches you something.
I used to let them use the propane gas barbeque but, I had this one guest who stayed here for a few days, and about 8.30 on the last morning he asked me if he could cook up a few sausages to take with him to snack on during his next drive. I had no issue with this, I got the BBQ going for him and left him to it!
That evening around 11.30 pm I had finished up for the night and I just happened to walk down through the BBQ area and I suddenly realised by heat coming from the BBQ, this bloody goofball had cooked up his snags, walked away and left the barbeque running.....almost 10 hours worth of LPG gone!
If guests want to cook something on the grill that is fine, I have just the appliance....it's a charcoal grill and I provide a bag of charcoal and a packet of fire lighters and an igniter on a chain for guest use. And if the supply bag runs out there is no need to be changing LPG cylinders which in many instances requires tools. Almost every convenience store stocks bags of charcoal, it's a better option yet still gives a barbeque flavour!
I decided then after 'Mr snag man' to only let guests use what they couldn't abuse. I figured electric was no good because they can leave that running also....although I believe now you can buy portable electric grills which do have a timer function.
I settled on charcoal because there is no expectation on the users part that they need to do anything other than cook their food. And I find they do actually get a kick out of making their own fire.
Once the cooking is done the grill will look after itself. When it's cool all I need to do is put the cover on the cooking surfaces to keep the vermin off, the same as I do with the BBQ. Simple and I can't get stung!
Cheers.......Rob
